Beijing Sends Maritime Patrol Ships to Diaoyu Islands Amid Dispute with Tokyo

Beijing has sent its maritime law enforcement through the maritime area of the Senkaku islands and unmanned aerial vehicles past outlying Japanese territory as Beijing ramps up strains following the Japanese prime minister’s remarks regarding the island of Taiwan.

Rights Enforcement Activities

On Sunday, the Chinese coast guard announced that its ships carried out a “lawful patrol operation” through the waters of the Diaoyu islands, which are under the control of Japan but also asserted as territory by China.

“Chinese maritime patrol unit 1307 conducted patrols within the territorial waters of the Diaoyu islands. This was a lawful patrol operation conducted by the China coast guard to uphold its rights and interests,” the statement said.

Diplomatic Spat

China and Japan have repeatedly faced off around the disputed territory but the latest activity come amid 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 might provoke a armed reaction from Japan.

That sparked an angry response from Beijing, which has indicated it demands a withdrawal from Takaichi.

Taiwan's Position

Beijing asserts the island as its sovereign land and intends to annex it under what it terms “unification”. It has left open 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 attack or invasion by China would threaten to spiral into a regional or global conflict, possibly drawing in the US and other allies including Tokyo, which has land just 110km (68 miles) from Taiwan.

Defense Operations

In Taiwan, the defence ministry reported this weekend that it had detected 30 Chinese military aircraft, seven navy ships and one “official” ship, 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 flying between the island and the Japan's territory 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 Taiwan’s air defence identification zone generally has been low in the past month.

Late on Saturday, the ministry said China had been carrying out another “combined military exercise” to “test our defensive capabilities”. It noted 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 Taipei says is an ongoing military pressure campaign.

Diplomatic Pressure

Tokyo has been facing mounting pressure from China since the Japanese official made her comments, with China’s consul general in the Japanese city prompting a formal protest 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 stated that any Tokyo's involvement would be certain to collapse.

Warning for Citizens

Late last week, Beijing 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 said on Saturday that flights to Tokyo could be cancelled without penalty.

Adding to the tensions, China’s government on Sunday urged its citizens to “carefully reconsider” studying in Japan, citing what it described as an volatile safety situation.

While the advice does not amount to a ban, a significant decrease in the number of Chinese students could have a negative impact on Japanese universities. A historic high of over 336,000 international students were studying in Japan last year, according to official data. They featured over 123,000 learners from China – by far the largest demographic.

Media Response

Earlier this weekend, a official press commentary accused Takaichi of staging a political stunt that was “not just dangerously provocative but fundamentally perverse”.

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

Policy Standpoints

The administration in Taipei says only its people can decide its future. Officials in Tokyo have previously avoided publicly mentioning Taiwan when addressing potential conflicts, maintaining a “strategic ambiguity” also favoured by Tokyo’s main security ally, 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, Beijing has also been increasing its political operations and its statements towards the island.
