Beijing Dispatches Coast Guard Ships to Diaoyu Islands Amid Tensions with Japan

Beijing has deployed its maritime law enforcement through the maritime area of the Senkaku islands and unmanned aerial vehicles near outlying Japanese territory as China escalates tensions following the Japan's leader's comments regarding the island of Taiwan.

Rights Enforcement Activities

This past Sunday, the Chinese coast guard announced that its vessels conducted a “rights enforcement patrol” through the waters of the Diaoyu islands, which are under the control of Japan but also claimed by Beijing.

“China coast guard vessel 1307 formation performed surveillance within the maritime jurisdiction of the Diaoyu islands. This was a lawful patrol operation conducted by the Chinese maritime authorities to protect its sovereign claims,” the statement said.

Bilateral Tensions

China and Japan have consistently clashed around the disputed territory but the latest activity occur during an intensifying diplomatic spat after the Japanese prime minister, the Japanese official, addressed lawmakers that if China attack the self-governing island of Taiwan it could trigger a armed reaction from Tokyo.

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

Taiwan's Position

China claims the island as its sovereign land and intends to annex it under what it describes as “reunification”. It has left open the use of force. The island's administration and citizens categorically refuse the prospect of Chinese rule – preferring to maintain the current situation without formally announcing independence, but pledging to protect their sovereignty if required.

An military assault 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 territory just 68 miles from the island.

Military Activity

In Taiwan, the defence ministry said on Sunday morning that it had observed 30 Chinese military aircraft, multiple naval vessels and one government vessel, which was likely the maritime patrol, active near the island over the previous day.

Official charts released showed up to three drones operating near the island and the Japan's territory off its northeastern shoreline, appearing to go unusually near to the nearby Japanese island. PLA movements there are occasional, but infrequent, and Beijing's defense operations in Taiwan’s air defence identification zone generally has been low in recent weeks.

Late on Saturday, the ministry said China had been conducting another “combined military exercise” to “harass the airspace and sea around us”. It noted the island had sent its own aircraft and ships to monitor the situation. The island documents these operations a couple of times a month as part of what Taipei says is an continuous strategic pressure.

Political Strain

Tokyo has been experiencing increased strain from Beijing since the Japanese official made her remarks, 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 China’s defence ministry stated that any Japanese intervention would be certain to collapse.

Warning for Citizens

On Friday, China advised its people to avoid visiting Japan, prompting Tokyo to urge Beijing to take “suitable actions”, though it provided no details.

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

Adding to the tensions, China’s government on the weekend advised students to rethink education plans in Japan, citing what it characterized as an unstable security environment.

Although not an outright prohibition, a significant decrease in the number of Chinese students could have a detrimental effect on Japanese universities. A historic high of over 336,000 international students were enrolled in Japanese schools last year, according to education statistics. They featured over 123,000 learners from China – by far the single biggest group.

Official Commentary

Earlier this weekend, a official press commentary accused Takaichi of staging a diplomatic maneuver that was “both reckless and fundamentally flawed”.

“A conflict between Japan and China would not be a limited skirmish; it would probably involve other nations, including the United States, and could rapidly escalate to a major confrontation with severe repercussions.”

Strategic Positions

The administration in Taipei says only its people can decide its future. Officials in Tokyo have traditionally refrained from publicly mentioning Taiwan when discussing such scenarios, maintaining a “deliberate vagueness” also preferred by Tokyo’s main security ally, the United States.

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