China Dispatches Coast Guard Vessels to Diaoyu Islands During Dispute with Tokyo

China has deployed its coast guard through the maritime area of the Diaoyu islands and unmanned aerial vehicles past remote Japanese territory as China escalates strains following the Japan's leader's comments regarding the island of Taiwan.

Rights Enforcement Activities

This past Sunday, the China's maritime patrol stated that its vessels carried out a “lawful patrol operation” through the territorial seas of the Senkaku, which are under the control of Tokyo but also claimed by China.

“Chinese maritime patrol unit 1307 performed surveillance within the maritime jurisdiction of the Diaoyu islands. This was a lawful patrol operation undertaken by the China coast guard to protect its sovereign claims,” officials declared.

Diplomatic Spat

China and Japan 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, addressed lawmakers that if Beijing assaults democratically ruled Taiwan it could trigger a armed reaction from Tokyo.

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

Taiwan's Position

Beijing asserts the island 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 prospect of Chinese rule – preferring to maintain the current situation without formally announcing independence, but vowing to defend themselves if required.

An military assault by Beijing would risk escalating into a regional or global conflict, possibly drawing in the United States and other partner nations including Tokyo, which has territory just 110km (68 miles) from the island.

Military Activity

In Taiwan, the military authorities reported this weekend that it had detected three dozen PLA planes, multiple naval vessels and one government vessel, which was probably the maritime patrol, active near the territory 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, appearing to go unusually near to Yonaguni. PLA movements there are occasional, but infrequent, and Chinese military activity in the island's ADIZ generally has been low in the past month.

Late on Saturday, the defense officials said China had been conducting another “joint combat patrol” to “test our defensive capabilities”. It added the island had dispatched military assets 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 ongoing military pressure campaign.

Diplomatic Pressure

Tokyo has been facing mounting pressure from Beijing since Takaichi made her comments, with Beijing's diplomatic representative in the Japanese city triggering an official complaint from Japan by commenting 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 stated that any Tokyo's involvement would be certain to collapse.

Warning for Citizens

On Friday, Beijing cautioned its citizens against travelling to Japan, leading Japan to request China to take “appropriate measures”, though it did not elaborate.

Multiple carriers from China said on Saturday that tickets to Japan could be cancelled without penalty.

In another escalation, China’s government on Sunday advised students to rethink education plans in Japan, citing what it characterized as an volatile safety situation.

Although not an outright prohibition, a significant decrease in the number of Chinese students could have a negative impact on academic institutions in Japan. A record 336,708 foreign nationals were studying in Japan last year, according to education statistics. They included more than 123,000 Chinese students – by far the largest demographic.

Media Response

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 nations, including the United States, and could quickly spiral into a major confrontation with unimaginable consequences.”

Strategic Positions

The administration in Taipei says the island's residents alone determine their destiny. Officials in Tokyo have traditionally refrained from publicly mentioning Taiwan when addressing potential conflicts, maintaining a “deliberate vagueness” also favoured by Tokyo’s main security ally, the United States.

Nevertheless, China’s ruling Communist party says the incorporation of the island with the mainland China is “unavoidable”, and portrays dissent as provocative. As it moves towards being capable of military annexation, Beijing has also been escalating its non-military activity and its statements towards the island.
