Argentina and Taiwan have hundreds of Chinese fishing boats in front of them. And no one has cast their nets into the sea to fish

In January 2026, a NASA satellite captured off the Argentine coast a strange image: a huge luminous spot floating in the middle of the South Atlantic, so bright that it looked like a city that had suddenly appeared on the ocean. From the ground nothing could be seen, but from space, however, it was impossible to ignore it.

The new floating wall. Last February we count what was seen through satellites, and since then it has not stopped repeating itself. For years, the world assumed that Chinese fishing boats were just that: boats dedicated to fishing. In 2026 that perception is changing rapidly. From the South China Sea to the South Atlantic, different governments are observing the same phenomenon: enormous chinese civil fleets remaining for weeks in strategic areas without clear fishing activity.

To be more exact, Argentina and Taiwan, separated by half a planet, now face a surprisingly similar situation: hundreds of Chinese vessels off their coasts whose function seems to go far beyond catching fish. What is disturbing is not only their presence, but the growing suspicion that Beijing is using apparently civilian ships like tools permanent geopolitical pressure and maritime surveillance.

Get paid to occupy the sea. I counted last April the ABC chain that investigations into the so-called Chinese “maritime militia” have shown the extent to which Beijing has professionalized this strategy. In the South China Sea, many ships receive state subsidies simply by staying in certain disputed areas.

The crews spend entire days at anchor, with hardly any fishing activity, while they help consolidate the Chinese presence around reefs, maritime routes or foreign military exercises such as Balikatan. For Western analysts, the goal is clear: physically saturate the sea with civilian vessels to intimidate rivals without the need to directly deploy traditional military units.

Taiwan discovers that anyone can be a problem. The pressure on Taiwan has made this tactic much more visible. This same month of May, Taipei expelled to the Chinese scientific vessel Tongji after detecting suspicious operations near the island. Officially he was carrying out oceanographic studies, but Taiwanese authorities suspect that collected strategic information on the seabed and nearby waters.

The incident reflected the great problem what Taiwan faces: It is already difficult to distinguish between civil ships, scientific ships, coast guard ships or military support platforms. That is why the island has even begun to adapt its coast guard patrol vessels to carry anti-ship missiles and act as part of national defense in the event of conflict.

Argentina sees the same pattern. Also in May, Reuters reported an extensive report. Thousands of kilometers from Asia, Argentina has been observing another enormous concentration of Chinese ships in front of its waters for years. Every season, about 200 fishing boats illuminate the South Atlantic during squid fishing, forming a gigantic floating city visible from space.

Although they officially carry out legal fishing activity outside the Argentine EEZ, Washington and part of the Argentine defense apparatus suspect that many of these vessels could be gathering intelligencemapping the seabed or measuring local surveillance capacity. The context makes the issue especially sensitive for a reason: the area is close to the Strait of Magellan and the access to Antarctica, two strategic areas of enormous geopolitical value.

Master the sea without shooting. For its part, China denies that there is any military use of these fleets and maintains that their ships act according to the law international. However, it is becoming evident to many countries that Beijing has found a very effective way to expand its maritime influence without resorting to open war.

In other words, the real change does not seem to be in the Chinese destroyers or aircraft carriers, but in the ability to bind a huge number of civilian ships in the ocean until the border between fishing, surveillance or strategic intimidation becomes unrecognizable. Meanwhile, Argentina and Taiwan are already seeing the same reality: one where there are hundreds of Chinese boats off its coast, and with each passing day it seems more strange that everyone has gone there so as not to cast their fishing nets.
