Tensions between China and Taiwan continued to escalate in October as Chinese naval and Coast Guard forces confronted American and Taiwanese vessels in separate incidents, underscoring Beijing's growing military pressure across the Western Pacific.

On October 20, China dispatched naval forces to monitor the USS Charleston, an American Independence-class littoral combat ship, after it entered waters near Sabina Shoal in the disputed Spratly Islands of the South China Sea.

The Chinese military's Southern Theater Command said its forces tracked and monitored the American warship, accusing the United States of entering waters Beijing claims as its territory without permission. Chinese naval officials demanded that Washington stop what they described as provocative military activities.

The USS Charleston's voyage came as the United States continued asserting its right to navigate international waters in the South China Sea, where Beijing has expanded its maritime claims and military presence. Washington has repeatedly challenged China's expansive territorial claims through freedom of navigation operations, although the Pentagon did not publicly identify this particular voyage as a formal operation.

The confrontation was accompanied by another incident farther north, where Taiwan accused a Chinese Coast Guard vessel of entering restricted waters near the Pratas Islands, also known as Dongsha.

Taiwanese authorities detected Chinese Coast Guard vessel 3102 around 5 a.m. on October 20. The vessel was operating with its Automatic Identification System switched off, making its movements less visible to other maritime traffic.

Taiwan dispatched its patrol ship Taichung to intercept the Chinese vessel, which entered restricted waters around 8 a.m. Taiwanese personnel repeatedly ordered the ship to leave.

The encounter also involved a direct dispute over Taiwan's political status. According to Taiwan's Coast Guard, the Chinese vessel broadcast that the Republic of China, Taiwan's official name, did not exist. Taiwanese personnel responded by declaring their country's sovereignty and independence and demanding that the Chinese ship immediately withdraw.

Taiwanese authorities said they had expelled Chinese Coast Guard vessels from waters surrounding the Pratas Islands on 12 occasions involving 15 vessel encounters during 2026.

The incidents reflect Beijing's broader strategy of increasing its military and maritime presence around Taiwan without necessarily initiating an outright military conflict. Since August 2022, the Chinese People's Liberation Army has maintained a significantly expanded operational presence around the island, regularly deploying warships and military aircraft into surrounding areas.

Chinese Coast Guard operations have also become an increasingly important part of the pressure campaign. Unlike conventional naval forces, Coast Guard vessels can operate under the appearance of civilian maritime law enforcement while challenging Taiwan's control over surrounding waters.

Beijing continues to claim Taiwan as part of its territory and has not ruled out using military force to bring the island under Chinese Communist Party control. Taiwan, which governs itself independently, maintains its own military, democratic institutions, and government.

China's expanding naval capabilities have also increased concerns throughout the region, particularly among American allies along the first island chain, which stretches from Japan through Taiwan and the Philippines.

The confrontation near Sabina Shoal also comes amid continuing disputes between China and the Philippines over competing territorial claims in the South China Sea. The United States maintains a mutual defense treaty with Manila that covers armed attacks against Philippine military forces and public vessels, including Coast Guard ships, in the South China Sea.

A 2016 international arbitration ruling rejected China's claims to historic rights over maritime areas beyond those permitted under international law. Beijing rejected the ruling and continues asserting its expansive claims.

For Washington, the growing confrontations present a challenge to maintaining freedom of navigation and deterring Chinese military expansion without allowing an incident at sea to escalate into a larger conflict.

Although neither the October 20 encounter near Sabina Shoal nor the confrontation near the Pratas Islands resulted in reported gunfire, the increasing frequency of these encounters raises the possibility of a miscalculation. With Chinese military and Coast Guard vessels operating more aggressively around Taiwan, the risk of an incident drawing in additional regional powers remains a significant security concern.
