China Sends Maritime Patrol Vessels to Diaoyu Islands During Dispute with Tokyo

China has deployed its coast guard into the waters of the Diaoyu islands and military drones past remote Japanese territory as Beijing ramps up strains following the Japan's leader's comments regarding the island of Taiwan.

Rights Enforcement Activities

This past Sunday, the Chinese coast guard announced that its vessels carried out a “lawful patrol operation” 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 conducted patrols within the maritime jurisdiction of the Senkaku islands. This was a lawful patrol operation conducted by the China coast guard to uphold its rights and interests,” officials declared.

Diplomatic Spat

Beijing and Tokyo 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 China attack the self-governing island of Taiwan it might provoke a military response from Japan.

That provoked a furious reaction from Beijing, which has indicated it demands a retraction from Takaichi.

Taiwan's Position

Beijing asserts the island as its own territory and plans to incorporate it under what it terms “reunification”. It has not ruled out the use of force. The island's administration and citizens categorically refuse the idea of Beijing's control – preferring to maintain the current situation without formally announcing independence, but vowing to defend themselves if necessary.

An military assault by Beijing would risk escalating into a regional or global conflict, possibly drawing in the United States and other allies including Japan, which has land just 68 miles from Taiwan.

Military Activity

In Taiwan, the defence ministry said on Sunday morning that it had detected three dozen PLA planes, seven navy ships and one “official” ship, which was likely the maritime patrol, operating around the territory over the past 24 hours.

Official charts released showed up to three drones flying between the island and the Japan's territory off its north-east coast, seeming to travel particularly close to Yonaguni. PLA movements there are not rare, but infrequent, and Beijing's defense operations in the island's ADIZ generally has been low in recent weeks.

Earlier this weekend, the ministry said China had been carrying out another “joint combat patrol” to “test our defensive capabilities”. It added Taiwan had sent its own aircraft and ships to track the developments. Taiwan documents these operations a few times monthly as part of what the Taiwanese government says is an continuous strategic pressure.

Political Strain

Japan has been facing mounting pressure from Beijing since the Japanese official made her remarks, with Beijing's diplomatic representative in the Japanese city triggering an official complaint from Japan by commenting that “those who interfere will face consequences”.

China then summoned the Japanese ambassador for the first occasion since 2023, and Beijing's military authorities declared that any Tokyo's involvement would be doomed to fail.

Travel and Education Advisory

Late last week, China advised its people to avoid visiting Japan, leading Japan to request China to take “appropriate measures”, though it provided no details.

Multiple carriers from China announced this weekend that tickets to Japan could be cancelled without penalty.

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

While the advice does not amount to a ban, a significant decrease in the number of Chinese students could have a negative impact on Japanese universities. A record 336,708 foreign nationals were studying in Japan last year, according to education statistics. They featured over 123,000 learners from China – by far the largest demographic.

Official Commentary

Earlier this weekend, 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 likely draw in other powers, including the US, and could quickly spiral into a large-scale conflict with severe repercussions.”

Strategic Positions

The administration in Taipei 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 mainland China is “unavoidable”, and casts any opposition to it as escalatory. As it moves towards being capable of military annexation, China has also been escalating its non-military activity and its rhetoric towards the island.
