Luxury was the last industry where Europe, because it was Europe, had a competitive advantage in China. Until now

For decades, China was known as the country where the world’s luxury products were made, not where they were designed. The “Made in China” lived years associated with mass productionto the workshops that supplied Europe and to the supply chains that kept the pace of the sector alive. The great Western houses dependedand still depend— of its manufacturing capacity. But what almost no one saw coming is that that same country, which built the industrial muscle of global luxury, would begin to develop its own brands capable of not only imitating, but directly competing. A market that no longer responds to the previous rules. According to data published by Bloombergspending on Western brands within China has slowed down in a huge market—around $49 billion—while several local firms are growing with a strength that surprises the industry itself: Laopu Gold, artisanal aesthetic jewelry, has multiplied by ten its online sales in just two years, compared to the 57 million of Van Cleef & Arpels, one of the most recognized names in Western fine jewelry. Songmont, specialized in bags with clean lines and minimalist design, is close to 90% growth in e-commerce. In contrast, Gucci’s drop in the same channel exceeds 50%. Mao Geping—a local brand with a strong Chinese theatrical aesthetic— doubles income by Bobbi Brown on the platform. And all this happens while giants like LVMH or Kering are experiencing sharp declines in the stock market compared to their highs in 2023 and 2021 respectively. As Chosun Biz points outmany consumers who previously reserved their large purchases for foreign brands are now choosing local firms. A simple phrase, but one that reveals a profound cultural change. Luxury is no longer defined only by Europe. The transformation is not explained solely by the economic context, because otherwise the phenomenon would be limited. However, local brands are succeeding because they offer something that the young Chinese consumer recognizes as their own: an aesthetic and a cultural story that does not seek to appear Western. There are different examples, such as Songmont building its brand around “oriental beauty” and designing spaces inspired by calligraphy. To Summer creates fragrances with ingredients that are part of Chinese sensory memory—tea, osmanthus, preserved citrus—and presents them in Jingdezhen porcelainindisputable reference of the country’s ceramics. ICICLE bases its entire design on principles of harmony and simplicity rooted in local philosophy. This approach connects with a generation that no longer considers European logos as automatic symbols of taste. They look for beauty, yes, but a beauty that belongs to their culture. Luxury Society adds that local brands They have become experts in building coherent, deep brand universes full of cultural references that are natural, not forced. Meanwhile, foreign firms have been trying to adapt for years, often with superficial interpretations of Chinese symbolism. The rise of national pride. EITHER guochao, born as a movement roots that vindicate the aesthetics and identity of the Asian giant. A term that has become a purchasing criterion for many young people. It is not about rejecting what is Western, but about valuing what arises in the country’s own companies. Western houses try to adapt. The big foreign brands have begun to react. Digitalizing document a change in the way in which Louis Vuitton, Prada or Loewe relate to Chinese culture: they no longer only launch thematic collections on Lunar New Year, but they open stores that interpret local architectural languages, collaborate with artisans of intangible cultural heritage, produce content about Chinese cities and organize parades in enclaves that dialogue with the country’s history. The reality is that they have to respond to an increasingly demanding market and a consumer who has reduced his enthusiasm for luxury in the midst of an uncertain economic climate, marked by youth unemployment and the fall of confidence. The point is that, although Western localization is increasingly sophisticated, Chinese brands have an advantage because they start from a native understanding of their own aesthetic. They are not imitating the global language of luxury: they are proposing a new one. From followers to creators. The ecosystem is reminiscent of the process that Japan experienced decades ago. As some analyzes showfirst came the fascination with European luxury, then an economic crisis, and finally the rise of local brands that redefined modern Japanese aesthetics. China is going through a similar cycle, but with a level of global ambition that Japan did not have from the beginning. Furthermore, the picture is complicated by another key movement: according to Luxury SocietyChinese luxury spending has not disappeared, but has shifted abroad following the post-pandemic reopening. Japan is now one of the favorite destinations, where up to 80% of customers in some luxury stores are Chinese, it also happens in Singapore and Thailand. This makes the sales decline within China seem more serious than it is. Even so, at home, the preference for local brands is a cultural phenomenon, not a situational one. Can Chinese luxury consolidate itself as a global competitor? The potential is there, but the challenges are great. According to figures cited by Bloombergno Chinese brand in the sector has yet exceeded 0.5% global share or 10 billion yuan in annual revenue. The growth of recent years starts from small bases and there is still no truly global Chinese brand. The economy doesn’t help either. Consumer confidence is fragile and an important part of the local boom depends on a cultural pride that could fluctuate if the domestic situation worsens. The brands themselves recognize, in interviews collected by the same medium, that they need international talent and expansion outside of China to consolidate themselves. However, their advantage is powerful: they dominate the supply chain, manufacturing and, now, increasingly, aesthetics. The case of Shajuanstudied by researchers at Fudan University, shows how vertically integrated brands can control design, production and narrative more effectively than many international firms. A new global aesthetic emerges from China. The Asian giant is no longer just a key market for Western luxury; It is a creator of trends, … Read more

The only advantage Apple could have in AI was its private cloud. It has been copied by the person we least expected

Google has presented Private AI Compute, its cloud infrastructure specially designed so that our conversations remain totally private and cannot be accessed by anyone else. Not even Google. Why is it important. The deployment that Google has announced will allow users of models like Gemini to use them without fear that their sensitive data – finances, health, private conversations – could end up being rescued and accessed by third parties. Idea copied from Apple. This type of infrastructure is an adaptation of the platform that Apple presented more than a year agoPrivate Cloud Compute, and that precisely focused on protecting those conversations by using the company’s future AI models. There are some differences, and for example Apple makes use of a concept of “verifiable transparency” that allows external researchers to audit security and privacy at any time cryptographically. At Google they use third-party verification, which is somewhat more limited as it is not open to the public to verify the running software. Tranquility as a sales argument. AI models are becoming more useful and also more personal and proactive, and that means that we also end up using them with data that may be more personal and sensitive to help us with a very specific question. Beyond ZDR. The problem is that when using the models everything we ask and they answer you can see —and even deduce—. There are ZDR (Zero Data Retention) modes in enterprise accounts from some AI providers, but having a cloud that “privatizes” those conversations is especially promising when it comes to being able to talk about everything with AI without restrictions. no fear of that data coming out of there. How this “privatization cloud” works. Those responsible for Google they explain that Private AI Compute is a “secure, fortified space for processing your data that keeps your data isolated and private to you.” The system uses several layers involving its TPUs and its Titanium Intelligence Enclaves (TIE) security chips. Our devices connect to that secure cloud environment through encryption and a cryptographic security mechanism called “remote attestation” that verifies the identity and integrity of that hardware environment to which we connect. Google also offers a detailed technical report on the operation of this infrastructure. Similar to running local models. The result is theoretically that for the user everything runs “locally” in terms of privacy. Features such as translation or audio summaries that Google offers in its services run directly on our devices: there is no data that travels to the cloud. The best of both worlds. The problem is that local AI models have limited performance, and Private AI Compute will allow you to have the best of both worlds: the power of the best AI models—which run in gigantic data centers—and the privacy guarantee of Google’s Private AI Compute. A surprising twist. This type of infrastructure means that these conversations are completely protected and that not even Google can access them. It’s a surprising turn of events, especially since for the last 25 years Google has made a living by collecting our data to apply it to its advertising model. This type of option goes in just the opposite direction, and it only remains to be seen how it will market such capability. Strategic approach. Curiously, this announcement comes days after we learned that the new version of Siri with AI It will be powered—at least, initially—by Gemini, Google’s AI model. Both companies have had a multimillion-dollar agreement for years to make Google the default search engine in Safari on iPhones and Macs, and now that alliance is apparently reinforced with the use of Google’s AI model to power the future version of Siri. In Xataka | The key to making the iPhone competitive in AI was right next door: imitating what Android had already done

Those who boast of using AI have an advantage over those who do not

In the workplace, today more than ever, using artificial intelligence can make a big difference. What was once a secret or a taboo among employees Now it is a clear advantage and some workers even take advantage of it to stand out. The change in mentality in recent years that has made those who use AI in their work processes “come out of the closet.” Now knowing how to use AI makes your bosses see you as a qualified employee that they want to keep. The change in perception. Until recently, admitting that AI was used at work was almost a synonym of cheatersomething that generated distrust among colleagues and bosses and, therefore, had to be hidden. However, as as detailed The Wall Street Journalnow the situation has been reversed. These AI users have become references, and influencers of AI for the rest of their colleagues, which earns them the respect of their superiors. According to the ‘2024 Labor Trends Index Annual Report‘ Elaborated by Microsoft, 79% of business leaders agree that AI adoption is essential to remain competitive, while 66% acknowledge that they would not hire someone without AI skills. On the other hand, 71% would prefer to hire a candidate with AI skills even if they have less experience in the position. It is no longer a taboo, it is a “must have“. Jensen Huang, CEO of NVIDIA, summarizes well this reality: “AI will not take your job, someone who knows how to use it will.” Although in practice it seems that, at least in certain sectors, yes he is doing it. As and how they assure more and more managers at major technology companies developing AI models, employees who have integrated AI into their daily workflow are already They don’t need to be programming experts. nor engineers. They have simply learned to use it themselves through trial and error to get just the result they need. “It takes practice to know how to write instructions. AI can do anything you want it to do, but it only knows as much as you tell it,” he told The Wall Street Journal Kevin Wei, software product manager and AI popularizer since your YouTube channel LiftoffPM. AI’s gifted students. More advanced AI users don’t just use these tools occasionally. The Microsoft studio revealed that 75% of so-called “white collar” employees use some type of AI in their daily tasks, and 90% say that this technology helps them save time. However, for these results to be really useful and not become a black hole junk contentit is necessary to have experienced much more than the rest with different uses of AI and seeks to constantly improve its methods so that AI becomes a central part of your workflow. “You have to train the AI ​​and create a context for it to really reach the desired level. Once you dedicate the necessary time to it, the feeling is incredibly magical,” he confirmed to the WSJ Michael Rueckert, a Claude power user who uses it in his work as a marketing and SEO optimization manager. If you don’t use AI there is no job. It is increasingly common for job offers to require fluency in the use of AI toolsin the same way that a few years ago it was required to have knowledge of office automation. The impact of mastering AI does not go unnoticed. According to data collected by the study ‘Global Workforce Hopes and Fears Survey 2025‘ prepared by the consulting firm PWC, employees with AI skills tend to receive better salaries, with an average 56% higher than their colleagues, which reflects greater professional valuation. In fact, large technology companies, which have been the first to implement AI there where they couldhave started a kind of template renewalfiring those employees who do not master AI tools by others who do. Your partner becomes your teacher. The gap between those who use AI and those who do not can also be reduced through training within the companies themselves. However, unlike other areas of knowledge, for the training of employees in AI, companies are betting on promoting collaboration between employees so that they learn from each other, as how he published Bloomberg. Collaborative learning experiences between employees, such as the one explained Tim Foley, head of AI adoption at Internacional Motors, demonstrates that these learning strategies in the use of AI are more accessible to more workers, enhancing not only individual but also collective performance. That is, employees always have a trusted teacher sitting at the next table.

Switzerland shows how to take advantage of it in the middle of winter

In the Swiss Alps, where the silence of winter often means months of ice and gray skies, a group of engineers is looking at how snowflakes can be transformed into energy. What was once an obstacle—the accumulation of snow on the solar panels—now becomes an opportunity. Their goal is as simple as it is ambitious: discover how winter can produce solar electricity. A solar laboratory. In these cold, bright valleys, the Federal Polytechnic School of Lausanne (EPFL) and the WSL Institute for Snow and Avalanche Research have developed a computational model to study how snow patterns affect the performance of photovoltaic systems in alpine environments. This is the first detailed model that simulates the interaction between snow and vertical solar structures in high mountains. The study, published in the magazine Cold Regions Science and Technologyfocuses on Helioplant, a vertical solar structure patented by Austrian company Ehoch2. Its design – a kind of cross with four solar wings – allows snow to be removed passively, without covering the panels and maintaining its efficiency in extreme conditions. Snow as part of the solution. The question is inevitable: how? The Lausanne team has discovered that snow not only blocks light: it also returns it. Its white surface acts as a natural mirror that reflects the Sun’s rays towards the panels, a phenomenon known as albedo effect. The challenge is finding the right spot. If snow accumulates too much, it blocks light and can damage structures. That is why researchers are seeking to redesign the way the panels are installed, to take advantage of the reflection without being buried under the ice. Seeking to understand snow. To understand it, scientists did not limit themselves to observing it: they decided to model it based on what we were already discussing. To do this, they used Snowbedfoam, a computational fluid dynamics (CFD) tool based on OpenFOAM, capable of simulating the transport and deposition of snow around solar structures. According to the studyis an Eulerian-Lagrangian solver that allows us to accurately represent how flakes move and accumulate in real environments. In hundreds of simulations, the team adjusted parameters such as the angle of inclination, the height of the panel above the ground, the spacing between units or its alignment with the wind. The results were revealing: the most efficient panels rise at least 0.6 meters above the ground, enough to prevent accumulated snow from blocking the release of new flakes. Hence the orientation as well. Panels aligned with the prevailing air currents stay clean as they carry away snow and prevent it from accumulating. But if they are rotated about 45°, protected areas are created where the flakes remain. As some French scientists have already confirmedair currents can be as useful a resource as sunlight itself. When the cold inspires energy. In other places they are also learning to listen to winter. In Norway, solar panels They rise vertically to look straight at the snow. In the Arctic city of Tromsø, 1,600 units cover more than 2,600 square meters, capturing both direct sunlight and that bouncing off the white ground. On the other side of the Atlantic, researchers from the University of Michigan test transparent coatings that prevent snow from adhering to the panels, even at –35 °C. Different solutions for the same learning: that the snow is not an obstacle, but part of the system. When winter also shines. Solar energy, a symbol of summer and the desert, is reinvented among glaciers and snow-capped peaks. What previously shut down production now multiplies it. What once blocked light now reflects it. The objective of these tests is not only to generate electricity, but to “create more efficient and snow-resistant photovoltaic systems.” In the words of the Lausanne researchersthe future of solar energy could lie in learning from snow, not fearing it. In the Alps, each flake is no longer an obstacle: it is a potential particle of energy. And in that silent gesture of snow reflecting light, Switzerland is testing the future of solar energy.

Google has solved problems in two hours that would take three years on a supercomputer. It’s the quantum advantage we needed

Google has taken a notable step into the field of quantum computing with a new algorithm called Quantom Echoes. This algorithm has been able to demonstrate for the first time a “practical and verifiable quantum advantage” that makes its quantum computer make fools of today’s large supercomputers. 13,000 times faster than a supercomputer. The new algorithm, called Quantum Echoes (“Quantum Echoes”), has made it possible to demonstrate that a quantum computer – based on Google’s Willow quantum chip— successfully executes a verifiable algorithm that exceeds the capacity of today’s large supercomputers. Thus, that computer managed to execute that algorithm 13,000 times faster than the best current classical supercomputer when executing similar code. “Quantum verifiability”. Google’s quantum supercomputer solved the problem in just over two hours, when in the second supercomputer most powerful in the world, Frontier, would have taken 3.2 years. But it also did it in a verifiable way: the result can be repeated in the quantum computer itself or in any other of similar caliber. Quantum echoes. The algorithm resembles an advanced echo: you send a signal to the quantum system, perturb a qubit, and then precisely reverse the evolution of the signal to “listen” to the resulting echo. This echo is special because it is amplified by constructive interference, a quantum phenomenon where waves add up to become stronger, which allows this effect to be precisely measured. The algorithm allows modeling the structure of systems in nature, from molecules to black holes. An achievement with a lot of Nobel Prize behind it. The milestone is based on decades of research in this area, including that carried out by the recent Nobel Prize winner, Michel H. Devoretwho is part of the Google team. Together with his colleagues John M. Martinis and John Clark he laid the foundations for this advance at the University of California at Berkeley in the mid-1980s. “Quantum verifiability”.

His discovery: the properties of quantum mechanics could also be observed in electrical circuits large enough to be seen with the naked eye. That gave rise to the creation of superconducting qubitswhich are the basic blocks with which Google has created (like other companies) its quantum computers. Devoret joined Google in 2023, thus strengthening the company’s trajectory in its search for the now famous “quantum supremacy”. Promising practical applications. The advance is directed directly to the solution of important problems in fields such as medicine or materials science. Quantum computing remains an experimental technology and faces a key challenge with error correction, but Quantum Echoes demonstrates that “quantum software” is advancing at a pace parallel to hardware. Google applied Quantum Echoes to a proof of concept experiment for Nuclear Magnetic Resonance. This technique acts as a “molecular microscope”, a powerful tool that will help design drugs or, for example, establish the molecular structure of new polymers. a marathon. This new milestone demonstrates the progress that this technology has made in recent years, but Google is not alone here. Microsoft or IBM have also made notable advances in recent years, and of course there are numerous startups both in the US like in china who work in this area.

Russia has found a key advantage to multiply the range of its most lethal weapon in Ukraine: Chinese factories

Last July Reuters was made with some documents that proved the scope of the help from Beijing to Moscow with the war in Ukraine as a backdrop. The proliferation of Russian drones was possible thanks to a system labeling called “industrial refrigeration units” during transportation, one that allowed sanctions imposed by the West to be bypassed through fictitious companies. Now we know something else: that there are entire factories dedicated to collaboration. The invisible industrial alliance. The war in Ukraine has entered a new phase in which Russia’s technological advantage on the battlefield increasingly depends on a network of factories and chinese suppliers. Although Beijing proclaims neutrality, the official customs data show a spectacular increase in exports of critical components (especially fiber optic cables and batteries lithium-ion) that have allowed Moscow to mass-build the wired drones that are transforming the balance of power on the front. These aircraft, operated through ultra-fine glass threads that unwind in flight up to more than twenty kilometers, They are almost immune to electronic warfare and have managed to breach Ukrainian defenses with an efficiency reminiscent of a silent industrial evolution. The Chinese quantitative leap. How much? counted the Washington Post that between May and August, Chinese exports of fiber optic cables to Russia multiplied tenfold, reaching 528,000 kilometers per month, while shipments of lithium-ion batteries climbed to $54 million. In contrast, Ukraine barely received a few tens of km of cable and a testimonial volume of batteries. For analysts, this asymmetry it is not coincidental: China has restricted the transfer of technologies to kyiv and its allies, but has opened the floodgates of the flow towards Moscowtransforming what were simple commercial components into decisive pieces of the Russian war machine. The combination of low cost, high production capacity and speed in developing prototypes makes Chinese factories a material extension of the Kremlin’s war effort, a “precision rearguard” capable of sustaining the offensive even under Western sanctions. The weapon against electronic chaos. we have been counting. Faced with Ukrainian dominance in FPV drones, Russia has found fiber optic models a devastating tool. As they do not depend on radio frequencies, these devices are impossible to block through interference, and their wiring guarantees total control even in environments saturated with electronic warfare. Moscow uses them to destroy logistics lines, command centers and jamming equipment before launching offensives terrestrial. Its scope (coinciding with the advances measured “by sections of cable”) illustrates how this technology defines the very geometry of the front. Since the Ukrainian withdrawal in the Kursk region, wired drones have been the protagonists of precision attacks, such as the registered in Kramatorsk on October 5, cementing a pattern of warfare in which electronic resistance has become useless. The new factories of conflict. After the withdrawal of the giant DJI of the Russian market in 2022, a constellation of minor Chinese manufacturers has taken up its space. Companies like Shenzhen Huaxin Energy either Nasmin Technologyofficially dedicated to civil products, have become major suppliers of batteries and motors for Russian assemblers. The signature Rustakt LLCone of the largest in the Russian military sector, imported from China more than 577 million dollars in pieces between July 2023 and December of the same year, a volume that reveals the scale of covert industrial support. In turn, Russian manufacturers as ASFPV or Stribog exhibit on their websites production lines located in Chinese territorywith personnel, machinery and labels in Mandarin, manufacturing ultralight coils 0.28 mm and 20 km range designed by Chinese engineers. It is a transnational industrial network that no contracts needed formal military to nourish the Russian war effort: the flow of trade is its camouflage. The dilemma of the West. We have also been counting. Despite the sanctions imposed by the United States and the European Union, the majority of these shipments are protected by the ambiguity of the products “dual use”whose civil application allows controls to be avoided. For NATO, China has become a “decisive facilitator” of Putin’s war, Brussels accuses it of selectively applying its own export rules and to tolerate traffic of components that supports the Russian military industry. Beijing, meanwhile, continues to proclaim its neutrality, while its industrial system benefits economically from the prolongation of the conflict. Its strategy is subtle but effective: it does not supply weapons, but the infrastructure that makes them possible. A strategic advantage. Taken together, the convergence between Russian ingenuity and Chinese manufacturing capacity has created a war ecosystem that combines improvisation with industrial efficiency. The fiber drones optics symbolize that symbiosis: cheap, adaptable and difficult to counter. By providing Russia with technological independence from sanctions and tactical superiority on the battlefield, China not only strengthens its strategic partner, but also redefines global balance of power around a new form of hybrid warfare, where factories and cables count as much as missiles. The result is a cumulative advantage that, in the long term, threatens to turn the Ukrainian front into a manufactured warfare laboratorysupported not so much by soldiers, but by production lines on the other side of the world.

While the world desperately seeks rare earth, China has an overwhelming advantage: it’s called Wem

It seems clear that it has begun A race On the planet: the search for Rare earths and the essential critical minerals for many of the sectors that mark the geopolitical agenda. The problem for 99.9% of nations is the same: when they seem to have reached a deposit there are already A Chinese flag. What is not usually explained so much is how Beijing does. The miliar origin. Deep in the mountains of center of China extends A monumental installation that transforms both the landscape and the global competition for strategic resources. It is a gigantic antenna of 500 kilowatts, with lines that are deployed over 80 and 120 kilometers, originally conceived to maintain communication with underwater underwater. This electromagnetic colossus, whose extension exceeds in five times the New York surfacehas been converted into a decisive instrument for the exploration of critical minerals, projecting signals capable of penetrating kilometers in the earth’s crust and revealing deposits that previously remained out of human reach. What began as a military project has become a Scientific and Technological Weapon which gives Beijing a remarkable advantage in the race for the resources that will define the future of energy and industry. Electromagnetic exploration. A study of the China Geological Survey (CGS), published in the Geophysical & Geochemical Exploration magazine, has detailed how the country has managed to monopolize Electromagnetic systems of ultra-high power. All platforms that exceed 100 kW are in Chinese territory, while the most powerful tool in the United States barely reaches 30 kW. The difference is not trivial: this technological leap has allowed Chinese geologists to discover in recent years sites of historical magnitude, such as the Greater gold deposit of the world, reserves Lithium ultra-extends and uranium veins in depths Never achieved. The research led by Chen Hui and his team affirms That these innovations consolidate China’s world position in electromagnetic exploration theory and technology, placing it far ahead of any western competitor. The challenge. As the superficial deposits of copper, lithium, cobalt and rare earths are exhausted, the exploration has moved to what geologists call The “Second Mineral Space”: An underground strip that extends between 500 and 2,000 meters deep. In this environment, the signs issued by mineral bodies are extremely weak and are usually buried under the cultural noise generated by electricity lines, urban infrastructure and extractive operations. The Chinese response has been to redefine the scale of prospecting: multiply the transmission power by above 100 kWflooding the subsoil with signs capable of crossing interference and reaching depths of up to 3,000 meters with unprecedented clarity. Advances in the subsoil cartography. The jump is not limited to power. While conventional techniques relied on two -dimensional models not suitable for complex structures, Chinese systems use Sensors distributed networks and multidirectional field sources that allow a real three -dimensional image of the subsoil. In the Jiama copper mine, in the Tibet, a controlled audio-magnetothelúrica tensorial study (CSAMT) reached unpublished resolutions at more than 3,000 meters, subsequently confirmed with drilling nuclei. These results They far exceeded to the Magnetotheluric of Natural Source, usually ineffective in saturated noise environments. The methods. One of the most prominent advances is the Electromagnetic method wide field, developed by Professor He Jishan, which allows you to obtain reliable data even in the so -called “nearby field zone”, where the records were not very useful. At the same time, the time-frequency electromagnetic systems are expanding the available information by measuring not only the resistance of the materials, but also its polarization and permeabilityessential parameters to distinguish between different types of deposits. The Wem project. And so we reach the clearest symbol of this ambition: The Wem project (Wireless Electromagnetic Method), whose colossal structure crosses China’s heart with two antenna lines arranged almost at right angles. This system, which began as a naval communication tool, has become the First electromagnetic transmitter of continental scale used in the prospecting of resources. In a national test carried out in 2023its signs were detected from Tibet to Interior Mongolia and Guangdong, more than 2,000 kilometers away. In the area of ​​Xiong’an there were magnetic fields up to seven times higher than the natural background noise, an unequivocal demonstration of the system’s capacity to impose itself on the most complex interference. Strategic advantage. In other words, with these Beijing technologies It is placed at the head of the struggle for the essential mineral resources for the energy transition and the green technologies: lithium for batteries, cobalt for high resistance alloys and rare earths essential in modern electronics. In contrast, most Western countries lack comparable systems and, except Russia, almost none use ultra-high power instruments in terrestrial prospecting. Even the most powerful teams manufactured in the West have been designed at China, which underlines the existing technological dependence. A new geopolitical board. China’s ability to identify deep deposits quickly Not only is it a scientific advantage, but also strategic. Control over technology and data places Beijing in a position to mark the rhythm of the discovery of resources in the coming decades. If you want, in a context where the energy transition redefines the global value chains, who controls access to lithium, cobalt and rare earth will control much of the industrial future. With the deployment of Giant antennas and electromagnetic systems Of unpublished power, China is making it clear that it does not intend to participate in the race: its goal is to win it.
