Beijing Dispatches Maritime Patrol Ships to Senkaku Islands Amid Dispute with Japan

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 remarks regarding Taiwan.

Patrol Operations

On Sunday, the Chinese coast guard stated that its vessels conducted a “lawful patrol operation” through the waters of the Senkaku, which are administered by Japan but also asserted as territory by Beijing.

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

Diplomatic Spat

China and Japan have consistently clashed around the islands but the latest activity come amid an escalating political dispute after the Japan's leader, Sanae Takaichi, told parliament that if China attack democratically ruled Taiwan it might provoke a armed reaction from Tokyo.

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

Taiwan's Position

China claims the island as its sovereign land and intends to annex it under what it describes as “unification”. It has not ruled out the military option. Taiwan’s government and citizens overwhelmingly reject the idea of Beijing's control – choosing to preserve the status quo without formally announcing independence, but pledging to protect their sovereignty if required.

An military assault by China would threaten to spiral into a regional or global conflict, potentially involving the United States and other allies including Japan, which has land just 110km (68 miles) from the island.

Military Activity

On the island, the military authorities said on Sunday morning that it had detected 30 Chinese military aircraft, multiple naval vessels and one government vessel, 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 unusually near to Yonaguni. Chinese military transits there are occasional, but uncommon, and Chinese military activity in Taiwan’s air defence identification zone generally has been minimal in recent weeks.

Late on Saturday, the ministry said China had been carrying out another “joint combat patrol” to “harass the airspace and sea around us”. It noted the island had dispatched military assets to track the developments. The island reports such Chinese patrols a few times monthly as part of what Taipei says is an ongoing military pressure campaign.

Political Strain

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

Beijing then summoned the Japanese ambassador for the first occasion since 2023, and China’s defence ministry stated that any Tokyo's involvement would be doomed to fail.

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 did not elaborate.

Three Chinese airlines announced this weekend that flights to Tokyo could be cancelled without penalty.

In another escalation, Beijing's administration on the weekend urged its citizens to “carefully reconsider” studying in Japan, citing what it described 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 detrimental effect on Japanese universities. A record 336,708 foreign nationals were studying in Japan last year, according to education statistics. They included more than 123,000 Chinese students – by far the largest demographic.

Official Commentary

Earlier this weekend, a official press commentary accused Takaichi of staging a political stunt that was “both reckless and fundamentally flawed”.

“A clash between Tokyo and Beijing 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 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 United States.

Nevertheless, Beijing's governing 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.
