China Sends Coast Guard Vessels to Senkaku Islands During Tensions with Tokyo

Beijing has deployed its maritime law enforcement through the waters of the Diaoyu islands and unmanned aerial vehicles near outlying Japanese territory as China ramps up tensions following the Japanese prime minister’s remarks regarding Taiwan.

Patrol Operations

On Sunday, the China's maritime patrol announced that its ships conducted a “rights enforcement patrol” through the waters of the Senkaku, which are under the control of Japan but also asserted as territory by China.

“China coast guard vessel 1307 formation performed surveillance within the maritime jurisdiction of the Senkaku islands. This was a lawful patrol operation conducted by the China coast guard to protect its sovereign claims,” the statement said.

Diplomatic Spat

Beijing and Tokyo have repeatedly faced off around the disputed territory but the latest activity occur during an intensifying diplomatic spat after the Japanese prime minister, the Japanese official, addressed lawmakers that if Beijing assaults the self-governing island of Taiwan it could trigger a armed reaction from Tokyo.

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

Island's Stance

Beijing asserts Taiwan as its sovereign land and intends to annex it under what it describes as “unification”. It has left open the military option. The island's administration and people overwhelmingly reject the prospect of Chinese rule – choosing to preserve the status quo without formally announcing independence, but vowing to defend themselves if required.

An military assault by China would risk escalating into a international confrontation, possibly drawing in the United States and other allies including Japan, which has territory just 110km (68 miles) from the island.

Defense Operations

On the island, the defence ministry reported this weekend that it had detected three dozen PLA planes, multiple naval vessels and one government vessel, which was probably the coast guard, operating around the territory over the past 24 hours.

Official charts released showed up to three drones flying between the island and the Japanese islands off its north-east coast, seeming to travel unusually near to Yonaguni. PLA movements there are occasional, 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 Beijing had been conducting another “joint combat patrol” to “test our defensive capabilities”. It noted the island had dispatched military assets to monitor the situation. Taiwan reports such Chinese patrols a couple of times a month as part of what the Taiwanese government says is an continuous strategic pressure.

Diplomatic Pressure

Japan has been facing mounting pressure from China since Takaichi made her remarks, with China’s consul general in Osaka triggering an official complaint from Japan by stating 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 Beijing's military authorities declared that any Japanese intervention would be certain to collapse.

Warning for Citizens

On Friday, China advised its people to avoid visiting Japan, prompting Tokyo to urge Beijing to take “appropriate measures”, though it did not elaborate.

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 described as an unstable security environment.

Although not an outright prohibition, 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 enrolled in Japanese schools last year, according to education statistics. 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 diplomatic maneuver that was “not just dangerously provocative but fundamentally perverse”.

“A clash between Tokyo and Beijing would not be a limited skirmish; it would probably involve other nations, including the US, and could quickly spiral into a major confrontation with unimaginable consequences.”

Strategic Positions

The government of Taiwan says the island's residents alone determine their destiny. 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, China’s ruling Communist party says the incorporation of the island with the mainland China is “unavoidable”, and portrays dissent as provocative. As it advances toward potential armed takeover, Beijing has also been escalating its non-military activity and its statements towards the island.
