Beijing Sends Maritime Patrol Ships to Diaoyu Islands Amid Tensions with Japan

China has sent its maritime law enforcement into the maritime area of the Senkaku islands and military drones past outlying Japan's territory as China ramps up tensions following the Japanese prime minister’s remarks regarding the island of Taiwan.

Rights Enforcement Activities

This past Sunday, the Chinese coast guard stated that its ships carried out a “lawful patrol operation” through the territorial seas of the Senkaku, which are under the control of Tokyo but also asserted as territory by China.

“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 uphold its rights and interests,” officials declared.

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, Sanae Takaichi, told parliament that if China attack democratically ruled Taiwan it could trigger a armed reaction from Japan.

That provoked a furious reaction from China, which has indicated it demands a retraction from the Japanese official.

Taiwan's Position

China claims Taiwan as its own territory and intends to annex it under what it terms “unification”. It has not ruled out the military option. Taiwan’s government and people categorically refuse the prospect of Chinese rule – preferring to maintain the status quo without explicitly declaring themselves independent, but pledging to protect their sovereignty if necessary.

An military assault by China would threaten to spiral into a international confrontation, possibly drawing in the United States and other partner nations including Japan, which has land just 68 miles from Taiwan.

Military Activity

On the island, the defence ministry reported this weekend that it had observed 30 Chinese military aircraft, seven navy ships and one “official” ship, which was likely the maritime patrol, active near the island over the past 24 hours.

Maps provided by the ministry showed up to three drones flying between Taiwan and the Japanese islands off its north-east coast, seeming to travel unusually near to the nearby Japanese island. PLA movements there are not rare, but uncommon, and Chinese military activity in the island's ADIZ generally has been minimal in recent weeks.

Late on Saturday, the defense officials said China had been carrying out another “combined military exercise” to “test our defensive capabilities”. It noted the island had dispatched military assets to monitor the situation. The island documents these operations a couple of times a month as part of what the Taiwanese government says is an continuous strategic pressure.

Political Strain

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

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

Travel and Education Advisory

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

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

Adding to the tensions, Beijing's administration on Sunday 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 dramatic reduction in the population of learners from China could have a negative impact on academic institutions in Japan. 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 Chinese state media editorial accused Takaichi of staging a political stunt that was “both reckless and fundamentally flawed”.

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

Policy Standpoints

The government of Taiwan says the island's residents alone determine their destiny. Officials in Tokyo 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.

Nevertheless, Beijing's governing party says the incorporation of the island with the People’s Republic of 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 statements towards Taiwan.
