China Dispatches Coast Guard Vessels to Senkaku Islands Amid Dispute with Tokyo

Beijing has sent its coast guard through the maritime area of the Senkaku islands and unmanned aerial vehicles past outlying Japanese territory as China ramps up strains over the Japan's leader's remarks regarding Taiwan.

Patrol Operations

This past Sunday, the Chinese coast guard stated that its vessels conducted 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 Diaoyu islands. This was a legitimate rights enforcement activity conducted by the Chinese maritime authorities to uphold its rights and interests,” officials declared.

Bilateral Tensions

Beijing and Tokyo have repeatedly faced off around the islands but the latest activity come amid an intensifying diplomatic spat after the Japanese prime minister, the Japanese official, told parliament that if Beijing assaults democratically ruled Taiwan it could trigger a military response from Japan.

That provoked a furious reaction from Beijing, which has signalled it expects a retraction from Takaichi.

Taiwan's Position

China claims Taiwan as its own territory and plans to incorporate it under what it describes as “unification”. It has left open the military option. The island's administration and citizens categorically refuse the prospect of Chinese rule – preferring to maintain the status quo without formally announcing independence, but vowing to defend themselves if required.

An attack or invasion by Beijing would risk escalating into a regional or global conflict, potentially involving the United States and other partner nations including Tokyo, which has land just 68 miles from Taiwan.

Defense Operations

On the island, the military authorities reported this weekend that it had detected three dozen PLA planes, seven navy ships and one “official” ship, which was probably the coast guard, operating around the island over the past 24 hours.

Maps provided by the ministry showed up to three drones operating near Taiwan and the Japanese islands off its north-east coast, seeming to travel unusually near to the nearby Japanese island. Chinese military transits there are not rare, but infrequent, and Beijing's defense operations in the island's ADIZ generally has been low in recent weeks.

Earlier this weekend, the defense officials said China had been conducting another “combined military exercise” 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.

Diplomatic Pressure

Tokyo has been experiencing increased strain from China since the Japanese official made her remarks, with Beijing's diplomatic representative in Osaka prompting a formal protest from Japan by stating 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 Beijing's military authorities declared that any Tokyo's involvement would be doomed to fail.

Warning for Citizens

On Friday, China advised its people to avoid visiting Japan, leading Japan to request China 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 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.

Official Commentary

Earlier this weekend, a official press commentary 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 small-scale encounter; it would likely draw in other nations, including the United States, and could quickly spiral into a major confrontation with unimaginable consequences.”

Strategic Positions

The administration in Taipei says only its people can decide its future. Officials in Tokyo have traditionally refrained from discussing the island openly when discussing such scenarios, maintaining a “strategic ambiguity” also favoured by Japan's primary defense partner, the United States.

Nevertheless, China’s ruling Communist party says the unification of Taiwan with the mainland China is “inevitable”, and portrays dissent as provocative. As it moves towards being capable of military annexation, China has also been increasing its political operations and its rhetoric towards the island.
