China Dispatches Coast Guard Vessels to Diaoyu Islands During Tensions with Tokyo

China has sent its coast guard into the maritime area of the Diaoyu islands and military drones past outlying Japanese territory as Beijing ramps up strains following the Japanese prime minister’s comments regarding the island of Taiwan.

Patrol Operations

This past Sunday, the Chinese coast guard stated that its vessels carried out a “lawful patrol operation” through the waters of the Diaoyu islands, which are administered by Japan but also claimed by Beijing.

“China coast guard vessel 1307 formation performed surveillance within the territorial waters of the Diaoyu islands. This was a legitimate rights enforcement activity conducted by the China coast guard to uphold its rights and interests,” the statement said.

Bilateral Tensions

Beijing and Tokyo have consistently clashed around the islands but the recent developments occur during an intensifying diplomatic spat after the Japanese prime minister, the Japanese official, addressed lawmakers that if China attack democratically ruled Taiwan it might provoke a military response from Japan.

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

Taiwan's Position

Beijing asserts Taiwan as its sovereign land and plans to incorporate it under what it terms “unification”. It has not ruled out the military option. The island's administration and citizens overwhelmingly reject the idea of Beijing's control – choosing to preserve the status quo without formally announcing independence, but pledging to protect their sovereignty if required.

An attack or invasion by China would risk escalating into a international confrontation, potentially involving the US and other partner nations including Japan, which has territory just 110km (68 miles) from Taiwan.

Military Activity

In Taiwan, the military authorities reported this weekend that it had observed 30 Chinese military aircraft, multiple naval vessels and one government vessel, which was probably the maritime patrol, active near the island over the previous day.

Official charts released showed up to multiple UAVs operating near Taiwan and the Japanese islands off its north-east coast, appearing to go unusually near to Yonaguni. Chinese military transits there are occasional, but uncommon, and Beijing's defense operations in the island's ADIZ generally has been minimal in recent weeks.

Earlier this weekend, the ministry said Beijing had been carrying out another “combined military exercise” to “harass the airspace and sea around us”. It noted the island had dispatched military assets to track the developments. Taiwan documents these operations a couple of times a month as part of what Taipei says is an ongoing military pressure campaign.

Political Strain

Japan has been facing mounting pressure from China since the Japanese official made her remarks, with China’s consul general in the Japanese city triggering an official complaint from Japan by stating that “those who interfere will face consequences”.

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

Warning for Citizens

Late last week, Beijing cautioned its citizens against travelling to Japan, prompting Tokyo to urge Beijing to take “appropriate measures”, though it provided no details.

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

In another escalation, Beijing's administration on Sunday urged its citizens to “carefully reconsider” studying in Japan, citing what it described as an unstable security environment.

While the advice does not amount to a ban, a significant decrease in the number of Chinese students 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 featured over 123,000 learners from China – by far the largest demographic.

Official Commentary

Late on Saturday, a Chinese state media editorial 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 United States, and could quickly spiral into a major confrontation with severe repercussions.”

Strategic Positions

The administration in Taipei says the island's residents alone determine their destiny. Officials in Tokyo have traditionally refrained from discussing the island openly when addressing potential conflicts, maintaining a “strategic ambiguity” also favoured by Japan's primary defense partner, the United States.

Nevertheless, Beijing's governing party says the unification of Taiwan with the People’s Republic of China is “unavoidable”, and portrays dissent as provocative. As it moves towards being capable of military annexation, Beijing has also been escalating its non-military activity and its rhetoric towards the island.
