China Dispatches Maritime Patrol Vessels to Diaoyu Islands During Dispute with Japan

China has deployed its coast guard through the waters of the Senkaku islands and military drones past outlying Japanese territory as Beijing ramps up tensions over the Japan's leader's remarks regarding the island of Taiwan.

Patrol Operations

This past Sunday, the Chinese coast guard stated that its ships conducted a “lawful patrol operation” through the waters of the Senkaku, which are under the control of Tokyo but also claimed by China.

“Chinese maritime patrol unit 1307 performed surveillance within the territorial waters of the Senkaku islands. This was a legitimate rights enforcement activity undertaken by the Chinese maritime authorities to protect its sovereign claims,” the statement said.

Diplomatic Spat

China and Japan have consistently clashed around the disputed territory but the recent developments come amid an escalating political dispute after the Japan's leader, Sanae Takaichi, told parliament that if Beijing assaults the self-governing island of Taiwan it might provoke a military response from Tokyo.

That sparked an angry response from China, which has indicated it demands a withdrawal from the Japanese official.

Island's Stance

Beijing asserts Taiwan as its sovereign land and plans to incorporate it under what it describes as “reunification”. It has not ruled out the military option. Taiwan’s government and citizens overwhelmingly reject the idea of Beijing's control – preferring to maintain the status quo without explicitly declaring themselves independent, but pledging to protect their sovereignty if required.

An attack or invasion by China 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 68 miles from Taiwan.

Military Activity

On the island, the military authorities reported this weekend that it had detected 30 Chinese military aircraft, seven navy ships and one government vessel, which was likely the maritime patrol, operating around the territory over the past 24 hours.

Maps provided by the ministry showed up to three drones operating near Taiwan and the Japanese islands off its northeastern shoreline, appearing to go unusually near to Yonaguni. PLA movements there are occasional, but infrequent, and Beijing's defense operations in Taiwan’s air defence identification zone generally has been minimal in the past month.

Earlier this weekend, the ministry said China had been conducting another “joint combat patrol” to “harass the airspace and sea around us”. It noted Taiwan had sent its own aircraft and ships to monitor the situation. The island reports such Chinese patrols a few times monthly as part of what the Taiwanese government says is an continuous strategic pressure.

Political Strain

Japan has been experiencing increased strain from Beijing since Takaichi made her comments, with Beijing's diplomatic representative in Osaka triggering an official complaint from Tokyo by stating 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 China’s defence ministry stated that any Japanese intervention 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 “suitable actions”, though it did not elaborate.

Multiple carriers from China announced this weekend that flights to Tokyo could be cancelled without penalty.

Adding to the tensions, Beijing's administration on Sunday advised students to rethink education plans in Japan, citing what it characterized as an unstable security environment.

While the advice does not amount to a ban, a dramatic reduction in the population of learners from China could have a detrimental effect on academic institutions in Japan. A record 336,708 foreign nationals were enrolled in Japanese schools last year, according to official data. They included more than 123,000 Chinese students – by far the largest demographic.

Media Response

Late on Saturday, a Chinese state media editorial charged the Japanese official with performing 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 United States, and could quickly spiral into a large-scale conflict with severe repercussions.”

Strategic Positions

The government of Taiwan says only its people can decide its future. Officials in Tokyo have previously avoided publicly mentioning Taiwan when addressing potential conflicts, 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 moves towards being capable of military annexation, Beijing has also been increasing its political operations and its rhetoric towards Taiwan.
