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

China has sent its maritime law enforcement into the maritime area of the Diaoyu islands and military drones past remote Japan's territory as China ramps up strains following the Japan's leader's comments regarding the island of Taiwan.

Patrol Operations

This past Sunday, the Chinese coast guard announced that its ships conducted a “lawful patrol operation” through the territorial seas of the Senkaku, which are administered by Japan but also asserted as territory by Beijing.

“Chinese maritime patrol unit 1307 performed surveillance within the maritime jurisdiction of the Senkaku islands. This was a legitimate rights enforcement activity undertaken by the China coast guard to uphold its rights and interests,” the statement said.

Bilateral Tensions

Beijing and Tokyo have consistently clashed around the islands but the latest activity occur during an escalating political dispute 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 Beijing, which has signalled it expects a withdrawal from the Japanese official.

Taiwan's Position

China claims the island as its own territory and plans to incorporate it under what it describes as “reunification”. It has left open the use of force. The island's administration and citizens overwhelmingly reject the idea of Beijing's control – preferring to maintain the current situation without formally announcing independence, but vowing to defend themselves if required.

An military assault by China would threaten to spiral into a regional or global conflict, potentially involving the US and other partner nations including Japan, which has territory just 68 miles from the island.

Defense Operations

On the island, the military authorities reported this weekend that it had detected 30 Chinese military aircraft, multiple naval vessels and one “official” ship, which was probably the coast guard, operating around the territory over the previous day.

Maps provided by the ministry showed up to three drones operating near Taiwan and the Japan's territory off its north-east coast, seeming to travel unusually near to the nearby Japanese island. Chinese military transits there are occasional, but infrequent, and Beijing's defense operations in Taiwan’s air defence identification zone generally has been low in the past month.

Late on Saturday, the ministry said China had been conducting another “combined military exercise” to “harass the airspace and sea around us”. It added Taiwan had dispatched military assets to monitor the situation. The island reports such Chinese patrols a few times monthly as part of what Taipei says is an ongoing military pressure campaign.

Diplomatic Pressure

Tokyo has been facing mounting pressure from China since the Japanese official made her remarks, with Beijing's diplomatic representative in the Japanese city triggering an official complaint from Tokyo by commenting that “the dirty head that sticks itself out must be cut off”.

China then called in Japan's diplomat for the first occasion since 2023, and China’s defence ministry declared that any Japanese intervention would be certain to collapse.

Warning for Citizens

Late last week, Beijing advised its people to avoid visiting Japan, leading Japan to request China to take “suitable actions”, 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, China’s government on the weekend advised students to rethink education plans in Japan, citing what it characterized as an unstable security environment.

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 enrolled in Japanese schools last year, according to official data. They featured over 123,000 learners from China – by far the single biggest group.

Media Response

Late on Saturday, a official press commentary accused Takaichi of staging a political stunt that was “not just dangerously provocative but fundamentally perverse”.

“A clash between Tokyo and Beijing would not be a limited skirmish; it would likely draw in other nations, including the US, and could rapidly escalate to a large-scale conflict with unimaginable consequences.”

Strategic Positions

The administration in Taipei says only its people can decide its future. Japanese leaders have traditionally refrained from discussing the island openly when addressing potential conflicts, maintaining a “strategic ambiguity” also preferred by Japan's primary defense partner, the United States.

However, Beijing's governing party says the incorporation of the island with the mainland China is “unavoidable”, and casts any opposition to it as escalatory. As it advances toward potential armed takeover, China has also been increasing its political operations and its statements towards the island.
