On Wednesday afternoon, Taiwan’s military published a video compilation of the PLA’s recent activity near Taiwan. In some of the footage, Chinese vessels can be seen just a short distance away from Taiwan’s military planes and ships. Meanwhile, a war simulation held by a Washington-based think tank showed that under most scenarios, China would be unable to take over Taiwan by force. The simulation posited a hypothetical Chinese attack in 2026, with the U.S. deciding to defend Taiwan.

On Wednesday afternoon, the military released a video compilation of their latest observations on the front line.

One clip shows a vessel numbered 525. This is the Chinese frigate Ma’anshan, with a displacement of 3,900 tons. Judging from the camera angle, the frigate seems to be only 100 yards, or around 91.4 meters away from the military personnel who shot the video footage. This is the closest the armed forces of both sides of the strait have come in the last few decades.

Another clip was captured by Taiwan’s Albatross unmanned aircraft, showing the Ma’anshan crossing paths with Taiwan’s An Yang destroyer. Experts say the distance between the two vessels appears to be less than 1 kilometer.

Over in the U.S., the Center for Strategic and International Studies conducted a war simulation of a Chinese attack on Taiwan in the year 2026. In the scenario the U.S. decided to help Taiwan against a Chinese attack. The Chinese side first fired against U.S. bases in Japan and Guam, and sunk two U.S. carriers in the first three weeks. In the next phase, Chinese troops landed on Taiwan, but were able to take just Southern Taiwan, or about one third of the island, before the amphibious operation was halted by the U.S. The results showed that under most scenarios, Taiwan can repel an invasion with U.S. support.
