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

Beijing has sent its maritime law enforcement through the maritime area of the Senkaku islands and unmanned aerial vehicles past remote Japan's territory as China ramps up tensions over the Japan's leader's comments regarding Taiwan.

Patrol Operations

This past Sunday, the Chinese coast guard announced that its vessels conducted a “rights enforcement patrol” through the territorial seas of the Senkaku, which are administered by Japan but also claimed by China.

“China coast guard vessel 1307 formation performed surveillance within the maritime jurisdiction of the Diaoyu islands. This was a lawful patrol operation undertaken by the Chinese maritime authorities to uphold its rights and interests,” officials declared.

Bilateral Tensions

China and Japan have consistently clashed around the disputed territory but the latest activity come amid an intensifying diplomatic spat after the Japanese prime minister, Sanae Takaichi, told parliament that if China attack democratically ruled Taiwan it might provoke a armed reaction from Japan.

That provoked a furious reaction from China, which has indicated it demands a withdrawal from Takaichi.

Island's Stance

Beijing asserts the island as its sovereign land and plans to incorporate it under what it describes as “reunification”. It has not ruled out the use of force. The island's administration and citizens categorically refuse the prospect of Chinese rule – choosing to preserve the status quo without explicitly declaring themselves independent, 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 partner nations including Tokyo, which has territory just 68 miles from Taiwan.

Military Activity

On the island, the military authorities reported this weekend that it had observed three dozen PLA planes, seven navy ships and one government vessel, which was likely the maritime patrol, operating around the island over the past 24 hours.

Maps provided by the ministry showed up to three drones operating near Taiwan and the Japan's territory off its north-east coast, seeming to travel particularly close to the nearby Japanese island. Chinese military transits there are occasional, but uncommon, and Beijing's defense operations in the island's ADIZ generally has been low in the past month.

Late on Saturday, the defense officials said Beijing had been carrying out another “combined military exercise” to “test our defensive capabilities”. It added Taiwan had sent its own aircraft and ships to monitor the situation. 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.

Diplomatic Pressure

Tokyo has been experiencing increased strain from Beijing since Takaichi made her remarks, with Beijing's diplomatic representative in Osaka triggering an official complaint from Japan 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 declared that any Tokyo's involvement 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 did not elaborate.

Three Chinese airlines announced this weekend that tickets to Japan could be cancelled without penalty.

Adding to the tensions, China’s government on the weekend advised students to rethink education plans in Japan, citing what it described as an volatile safety situation.

Although not an outright prohibition, a dramatic reduction in the population of learners from China could have a detrimental effect on academic institutions in Japan. A historic high of over 336,000 international students 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 diplomatic maneuver that was “both reckless and fundamentally flawed”.

“A conflict between Japan and China would not be a small-scale encounter; it would probably involve other powers, including the US, and could quickly spiral into a large-scale conflict with unimaginable consequences.”

Policy Standpoints

The government of Taiwan says the island's residents alone determine their destiny. 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, China’s ruling Communist party says the incorporation of the island with the People’s Republic of China is “inevitable”, and casts any opposition to it as escalatory. As it moves towards being capable of military annexation, Beijing has also been escalating its non-military activity and its statements towards the island.
