China Dispatches Coast Guard Ships to Senkaku Islands Amid Dispute with Tokyo

China has deployed its coast guard into the waters of the Senkaku islands and military drones past remote Japan's territory as China escalates strains following the Japanese prime minister’s comments regarding Taiwan.

Rights Enforcement Activities

This past Sunday, the China's maritime patrol announced that its ships conducted a “lawful patrol operation” through the territorial seas of the Senkaku, which are under the control of Japan but also claimed by Beijing.

“Chinese maritime patrol unit 1307 performed surveillance within the territorial waters of the Senkaku islands. This was a lawful patrol operation undertaken by the Chinese maritime authorities to protect its sovereign claims,” officials declared.

Bilateral Tensions

China and Japan have consistently clashed around the disputed territory but the recent developments occur during an intensifying diplomatic spat after the Japan's leader, the Japanese official, addressed lawmakers that if Beijing assaults democratically ruled Taiwan it could trigger a armed reaction from Tokyo.

That provoked a furious reaction from China, which has signalled it expects a withdrawal from Takaichi.

Island's Stance

China claims the island as its own territory and plans to incorporate it under what it terms “unification”. It has not ruled out the military option. The island's administration and people categorically refuse the idea of Beijing's control – preferring to maintain the current situation without formally announcing independence, but vowing to defend themselves if required.

An attack or invasion by Beijing would risk escalating into a regional or global conflict, possibly drawing in the US and other allies including Tokyo, which has land just 68 miles from Taiwan.

Defense Operations

In Taiwan, the military authorities said on Sunday morning that it had detected three dozen PLA planes, seven navy ships and one government vessel, which was likely the coast guard, active near the island over the past 24 hours.

Maps provided by the ministry showed up to multiple UAVs operating near the island and the Japanese islands off its northeastern shoreline, seeming to travel unusually near to the nearby Japanese island. PLA movements there are occasional, but uncommon, and Beijing's defense operations in the island's ADIZ generally has been minimal in the past month.

Earlier this weekend, the ministry said Beijing had been carrying out another “joint combat patrol” to “test our defensive capabilities”. It added the island had sent its own aircraft and ships to monitor the situation. Taiwan reports such Chinese patrols a few times monthly as part of what Taipei says is an continuous strategic pressure.

Political Strain

Japan has been facing mounting pressure from China since the Japanese official made her comments, with Beijing's diplomatic representative in Osaka prompting a formal protest from Japan by stating that “those who interfere will face consequences”.

China then called in Japan's diplomat for the first occasion since 2023, and China’s defence ministry stated that any Tokyo's involvement would be doomed to fail.

Travel and Education Advisory

On Friday, Beijing cautioned its citizens against travelling to Japan, prompting Tokyo to urge Beijing to take “appropriate measures”, though it provided no details.

Three Chinese airlines said on Saturday that flights to Tokyo could be cancelled without penalty.

In another escalation, Beijing's administration on the weekend advised students to rethink education plans in Japan, citing what it described as an unstable security environment.

While the advice does not amount to a ban, a dramatic reduction in the number of Chinese students could have a negative impact on academic institutions in Japan. A record 336,708 foreign nationals were enrolled in Japanese schools last year, according to official data. They included more than 123,000 Chinese students – by far the single biggest group.

Official Commentary

Late on Saturday, a Chinese state media editorial charged the Japanese official with performing a diplomatic maneuver that was “not just dangerously provocative but fundamentally perverse”.

“A conflict between Japan and China would not be a limited skirmish; it would likely draw in other powers, including the United States, and could quickly spiral into a large-scale conflict with severe repercussions.”

Strategic Positions

The administration in Taipei says the island's residents alone determine their destiny. Officials in Tokyo have previously avoided publicly mentioning Taiwan when addressing potential conflicts, maintaining a “strategic ambiguity” also preferred by Tokyo’s main security ally, the US.

Nevertheless, Beijing's governing party says the incorporation of the island with the People’s Republic of China is “unavoidable”, and portrays dissent as provocative. As it advances toward potential armed takeover, Beijing has also been escalating its non-military activity and its statements towards Taiwan.
