China Dispatches Maritime Patrol Vessels to Diaoyu Islands Amid Tensions with Japan

China has deployed its maritime law enforcement into the maritime area of the Senkaku islands and military drones near outlying Japanese territory as Beijing ramps up strains following the Japanese prime minister’s comments regarding Taiwan.

Rights Enforcement Activities

This past Sunday, the China's maritime patrol stated that its ships carried out a “rights enforcement patrol” through the waters of the Senkaku, which are under the control of Tokyo but also asserted as territory by Beijing.

“Chinese maritime patrol unit 1307 conducted patrols within the territorial waters of the Senkaku islands. This was a lawful patrol operation conducted by the Chinese maritime authorities to protect its sovereign claims,” officials declared.

Bilateral Tensions

China and Japan have repeatedly faced off around the islands but the latest activity occur during an escalating political dispute after the Japan's leader, the Japanese official, addressed lawmakers that if China attack the self-governing island of Taiwan it could trigger a military response from Japan.

That provoked a furious reaction from Beijing, which has indicated it demands a withdrawal from the Japanese official.

Taiwan's Position

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. Taiwan’s government and people overwhelmingly reject the idea of Beijing's control – preferring to maintain the current situation without formally announcing independence, but pledging to protect their sovereignty if necessary.

An military assault 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 110km (68 miles) from Taiwan.

Defense Operations

On the island, the defence ministry reported this weekend that it had detected 30 Chinese military aircraft, seven navy ships and one “official” ship, which was likely the coast guard, operating around the island over the past 24 hours.

Official charts released showed up to three drones flying between Taiwan and the Japanese islands off its north-east coast, appearing to go unusually near to Yonaguni. PLA movements there are not rare, but uncommon, and Beijing's defense operations in Taiwan’s air defence identification zone generally has been low in recent weeks.

Earlier this weekend, the ministry said China had been carrying out another “combined military exercise” to “test our defensive capabilities”. It added the island 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.

Diplomatic Pressure

Japan has been experiencing increased strain from Beijing since the Japanese official made her comments, 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”.

Beijing then summoned the Japanese ambassador for the first occasion since 2023, and Beijing's military authorities stated that any Japanese intervention would be certain to collapse.

Warning for Citizens

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

Multiple carriers from China announced this weekend that tickets to Japan could be refunded or changed for free.

In another escalation, China’s government 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 dramatic reduction in the number of Chinese students could have a detrimental effect on academic institutions in Japan. 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 single biggest group.

Media Response

Late on Saturday, a official press commentary charged the Japanese official with performing a diplomatic maneuver 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 United States, and could rapidly escalate to a major confrontation with severe repercussions.”

Policy Standpoints

The government of Taiwan says only its people can decide its future. Japanese leaders have traditionally refrained from publicly mentioning Taiwan when discussing such scenarios, maintaining a “deliberate vagueness” also favoured by Japan's primary defense partner, the US.

However, Beijing's governing party says the incorporation of the island with the mainland China is “inevitable”, and portrays dissent as provocative. As it advances toward potential armed takeover, China has also been escalating its non-military activity and its rhetoric towards Taiwan.
