China Sends Maritime Patrol Vessels to Diaoyu Islands Amid Dispute with Tokyo

China has deployed its coast guard into the maritime area of the Diaoyu islands and military drones near remote Japan's territory as Beijing ramps up strains over the Japan's leader's comments regarding Taiwan.

Rights Enforcement Activities

This past Sunday, the China's maritime patrol stated that its vessels conducted a “rights enforcement patrol” through the waters of the Senkaku, which are administered by Tokyo but also claimed by China.

“Chinese maritime patrol unit 1307 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.

Diplomatic Spat

Beijing and Tokyo have repeatedly faced off 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 the self-governing island of Taiwan it could trigger a military response from Tokyo.

That provoked a furious reaction from Beijing, which has signalled it expects a retraction from the Japanese official.

Island's Stance

Beijing asserts Taiwan as its own territory and intends to annex it under what it terms “unification”. It has left open the use of force. Taiwan’s government and people overwhelmingly reject 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 Beijing would threaten to spiral into a international confrontation, possibly drawing in the United States and other partner nations including Tokyo, which has land just 110km (68 miles) from Taiwan.

Military Activity

In Taiwan, the military authorities said on Sunday morning that it had observed 30 Chinese military aircraft, seven navy ships and one government vessel, which was probably the maritime patrol, operating around the island over the previous day.

Maps provided by the ministry 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. 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.

Earlier this weekend, the ministry said Beijing had been conducting another “combined military exercise” to “test our defensive capabilities”. It noted Taiwan had dispatched military assets to monitor the situation. The island reports such Chinese patrols a few times monthly as part of what Taipei says is an ongoing military pressure campaign.

Political Strain

Japan has been facing mounting pressure from China since Takaichi made her remarks, with China’s consul general in Osaka prompting a formal protest from Tokyo 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 declared that any Japanese intervention would be doomed to fail.

Travel and Education Advisory

Late last week, Beijing cautioned its citizens against travelling to Japan, leading Japan to request China to take “suitable actions”, though it did not elaborate.

Three Chinese airlines said on Saturday that flights to Tokyo could be refunded or changed for free.

Adding to the tensions, Beijing's administration on the weekend urged its citizens to “carefully reconsider” studying in Japan, citing what it characterized as an volatile safety situation.

Although not an outright prohibition, a significant decrease in the population of learners from China could have a detrimental effect on academic institutions in Japan. A record 336,708 foreign nationals were studying in Japan last year, according to official data. They included more than 123,000 Chinese students – by far the single biggest group.

Official Commentary

Late on Saturday, a official press commentary accused Takaichi of staging a diplomatic maneuver that was “not just dangerously provocative but fundamentally perverse”.

“A conflict between Japan and China would not be a limited skirmish; it would probably involve other powers, including the US, and could quickly spiral into a major confrontation with severe repercussions.”

Strategic Positions

The government of Taiwan says the island's residents alone determine their destiny. Officials in Tokyo have traditionally refrained from discussing the island openly when discussing such scenarios, maintaining a “strategic ambiguity” also favoured by Tokyo’s main security ally, 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 Taiwan.
