Beijing Dispatches Maritime Patrol Ships to Senkaku Islands Amid Tensions with Tokyo

Beijing has sent its coast guard through the maritime area of the Diaoyu islands and unmanned aerial vehicles past remote Japan's territory as China ramps up tensions over the Japanese prime minister’s comments regarding Taiwan.

Patrol Operations

This past Sunday, the China's maritime patrol announced that its vessels carried out a “rights enforcement patrol” through the waters of the Senkaku, which are under the control of Tokyo but also asserted as territory 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 China coast guard to protect its sovereign claims,” the statement said.

Diplomatic Spat

Beijing and Tokyo have consistently clashed around the disputed territory but the recent developments come amid an escalating political dispute after the Japan's leader, the Japanese official, addressed lawmakers that if China attack the self-governing island of Taiwan it might provoke a armed reaction from Tokyo.

That sparked an angry response from China, which has signalled it expects a retraction from the Japanese official.

Taiwan's Position

China claims Taiwan as its own territory and plans to incorporate it under what it describes as “reunification”. It has left open the military option. The island's administration and citizens categorically refuse the prospect of Chinese rule – choosing to preserve the current situation without formally announcing independence, but pledging to protect their sovereignty if required.

An attack or invasion by Beijing would threaten to spiral into a international confrontation, possibly drawing in the United States and other allies including Tokyo, which has territory just 68 miles from Taiwan.

Defense Operations

In Taiwan, the defence ministry said on Sunday morning that it had observed three dozen PLA planes, seven navy ships and one government vessel, which was likely the maritime patrol, operating around the territory over the previous day.

Maps provided by the ministry showed up to multiple UAVs operating near the island and the Japan's territory off its north-east coast, appearing to go unusually near to the nearby Japanese island. PLA movements there are occasional, but infrequent, and Beijing's defense operations in Taiwan’s air defence identification zone generally has been low in recent weeks.

Earlier this weekend, the defense officials said Beijing had been conducting another “combined military exercise” to “harass the airspace and sea around us”. It noted the island had sent its own aircraft and ships to track the developments. Taiwan documents these operations a few times monthly as part of what Taipei says is an continuous strategic pressure.

Political Strain

Tokyo has been facing mounting pressure from Beijing since Takaichi made her remarks, with Beijing's diplomatic representative in Osaka prompting a formal protest from Japan by commenting that “the dirty head that sticks itself out must be cut off”.

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

Warning for Citizens

Late last week, China advised its people to avoid visiting Japan, prompting Tokyo to urge Beijing to take “suitable actions”, though it did not elaborate.

Three Chinese airlines announced this weekend that flights to Tokyo could be refunded or changed for free.

Adding to the tensions, Beijing's administration on Sunday advised students to rethink education plans in Japan, citing what it characterized as an unstable security environment.

Although not an outright prohibition, a dramatic reduction in the number of Chinese students could have a negative impact on Japanese universities. A historic high of over 336,000 international students were studying in Japan 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 official press commentary 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 small-scale encounter; it would probably involve other powers, including the United States, and could quickly spiral into a major confrontation with severe repercussions.”

Strategic Positions

The government of Taiwan says only its people can decide its future. Japanese leaders have traditionally refrained from publicly mentioning Taiwan when addressing potential conflicts, maintaining a “strategic ambiguity” also favoured by Japan's primary defense partner, the US.

Nevertheless, China’s ruling Communist party says the unification of Taiwan with the People’s Republic of China is “unavoidable”, and portrays dissent as provocative. As it moves towards being capable of military annexation, China has also been escalating its non-military activity and its rhetoric towards the island.
