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

Beijing has deployed its coast guard through the waters of the Senkaku islands and unmanned aerial vehicles past remote Japanese territory as China ramps up strains following the Japanese prime minister’s remarks regarding the island of Taiwan.

Rights Enforcement Activities

This past Sunday, the Chinese coast guard announced that its ships conducted 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.

“China coast guard vessel 1307 formation conducted patrols within the maritime jurisdiction of the Senkaku islands. This was a legitimate rights enforcement activity undertaken by the China coast guard to uphold its rights and interests,” the statement said.

Bilateral Tensions

China and Japan have consistently clashed around the disputed territory but the latest activity come amid an intensifying diplomatic spat after the Japanese prime minister, Sanae Takaichi, addressed lawmakers that if Beijing assaults democratically ruled Taiwan it might provoke a armed reaction from Tokyo.

That provoked a furious reaction from China, which has signalled it expects a retraction from Takaichi.

Taiwan's Position

Beijing asserts the island as its own territory and plans to incorporate it under what it describes as “reunification”. It has left open the military option. Taiwan’s government and citizens categorically refuse the prospect of Chinese rule – choosing to preserve the status quo without formally announcing independence, but pledging to protect their sovereignty if necessary.

An attack or invasion by Beijing would threaten to spiral into a regional or global conflict, possibly drawing in the United States and other allies including Japan, which has land just 68 miles from the island.

Military Activity

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

Official charts released showed up to multiple UAVs flying between 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 minimal in the past month.

Late on Saturday, the defense officials said Beijing had been carrying out 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 China since the Japanese official made her comments, with China’s consul general in the Japanese city triggering an official complaint from Japan by commenting that “those who interfere will face consequences”.

China then summoned the Japanese ambassador for the first occasion since 2023, and China’s defence ministry declared that any Tokyo's involvement would be doomed to fail.

Warning for Citizens

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

Three Chinese airlines announced this weekend that tickets to Japan could be refunded or changed for free.

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.

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 official data. They featured over 123,000 learners from China – by far the largest demographic.

Media Response

Late on Saturday, a official press commentary charged the Japanese official with performing a diplomatic maneuver that was “both reckless and fundamentally flawed”.

“A conflict between Japan and China would not be a limited skirmish; it would likely draw in other nations, including the US, and could rapidly escalate to a large-scale conflict with severe repercussions.”

Policy Standpoints

The government of Taiwan says only its people can decide its future. Japanese leaders have previously avoided publicly mentioning Taiwan when discussing such scenarios, maintaining a “strategic ambiguity” also preferred by Japan's primary defense partner, the United States.

However, China’s ruling Communist party says the unification of Taiwan with the People’s Republic of 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 the island.
