China Dispatches Maritime Patrol Ships to Senkaku Islands During Dispute with Japan

Beijing has deployed its coast guard into the maritime area of the Senkaku islands and military drones near outlying Japanese territory as China escalates tensions following the Japanese prime minister’s comments regarding Taiwan.

Rights Enforcement Activities

This past Sunday, the China's maritime patrol announced that its ships carried out a “lawful patrol operation” through the territorial seas of the Diaoyu islands, which are under the control of Tokyo but also asserted as territory by China.

“China coast guard vessel 1307 formation performed surveillance within the territorial waters of the Senkaku islands. This was a lawful patrol operation conducted by the Chinese maritime authorities to protect its sovereign claims,” 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 Japanese prime minister, the Japanese official, told parliament that if Beijing assaults democratically ruled Taiwan it might provoke a armed reaction from Japan.

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

Taiwan's Position

China claims Taiwan as its own territory and plans to incorporate it under what it terms “reunification”. It has not ruled out the military option. Taiwan’s government and citizens categorically refuse the idea of Beijing's control – preferring to maintain the current situation without formally announcing independence, but pledging to protect their sovereignty if required.

An attack or invasion by China would threaten to spiral into a regional or global conflict, possibly drawing in the US and other allies including Japan, which has land just 110km (68 miles) from the island.

Defense Operations

On the island, the defence ministry said on Sunday morning that it had observed three dozen PLA planes, multiple naval vessels and one “official” ship, which was likely the coast guard, active near the island over the previous day.

Official charts released showed up to three drones operating near Taiwan and the Japan's territory off its northeastern shoreline, seeming to travel particularly close to the nearby Japanese island. PLA movements there are not rare, but infrequent, and Chinese military activity in Taiwan’s air defence identification zone generally has been minimal in recent weeks.

Earlier this weekend, the defense officials said Beijing had been conducting another “combined military exercise” to “test our defensive capabilities”. It added Taiwan had sent its own aircraft and ships to track the developments. The island reports such Chinese patrols 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 China since Takaichi made her comments, 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 China’s defence ministry declared that any Japanese intervention would be certain to collapse.

Warning for Citizens

On Friday, Beijing cautioned its citizens against travelling to Japan, prompting Tokyo to urge Beijing to take “appropriate measures”, though it provided no details.

Three Chinese airlines said on Saturday that tickets to Japan could be cancelled without penalty.

In another escalation, Beijing's administration on Sunday urged its citizens to “carefully reconsider” studying in Japan, citing what it characterized as an unstable security environment.

Although not an outright prohibition, a dramatic reduction in the number of Chinese students could have a negative impact on Japanese universities. A historic high of over 336,000 international students were enrolled in Japanese schools last year, according to official data. They included more than 123,000 Chinese students – by far the largest demographic.

Media Response

Earlier this weekend, a official press commentary charged the Japanese official with performing a political stunt that was “not just dangerously provocative but fundamentally perverse”.

“A clash between Tokyo and Beijing would not be a small-scale encounter; it would probably involve other powers, including the US, and could rapidly escalate to a major confrontation with severe repercussions.”

Policy Standpoints

The government of Taiwan says only its people can decide its future. Japanese leaders have traditionally refrained from discussing the island openly when discussing such scenarios, maintaining a “deliberate vagueness” also preferred by Japan's primary defense partner, the US.

However, Beijing's governing party says the unification of Taiwan with the mainland China is “unavoidable”, and portrays dissent as provocative. As it moves towards being capable of military annexation, Beijing has also been increasing its political operations and its statements towards the island.
