China Dispatches Maritime Patrol Ships to Senkaku Islands Amid Tensions with Japan

China has sent its coast guard through the maritime area of the Diaoyu islands and military drones past outlying Japan's territory as China escalates strains following the Japan's leader's comments regarding Taiwan.

Rights Enforcement Activities

This past Sunday, the Chinese coast guard announced that its ships conducted a “rights enforcement patrol” through the waters of the Diaoyu islands, which are administered by Tokyo 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 undertaken by the China coast guard to uphold its rights and interests,” officials declared.

Bilateral Tensions

Beijing and Tokyo have repeatedly faced off around the islands but the recent developments occur during an escalating political dispute after the Japanese prime minister, Sanae Takaichi, told parliament that if China attack the self-governing island of Taiwan it might provoke a military response from Japan.

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

Taiwan's Position

Beijing asserts Taiwan as its sovereign land and plans to incorporate it under what it terms “reunification”. It has left open the use of force. The island's administration and citizens overwhelmingly reject the prospect of Chinese rule – preferring to maintain the current situation without formally announcing independence, but pledging to protect their sovereignty if required.

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

Military Activity

On the island, the military authorities reported this weekend that it had detected three dozen PLA planes, 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 multiple UAVs flying between the island and the Japan's territory off its northeastern shoreline, appearing to go particularly close to Yonaguni. Chinese military transits there are occasional, but infrequent, and Chinese military activity in Taiwan’s air defence identification zone generally has been minimal in recent weeks.

Late on Saturday, the ministry said Beijing had been conducting another “combined military exercise” to “test our defensive capabilities”. It added Taiwan had dispatched military assets to monitor the situation. Taiwan reports such Chinese patrols a few times monthly as part of what the Taiwanese government says is an continuous strategic pressure.

Diplomatic Pressure

Japan has been experiencing increased strain from China since Takaichi made her comments, with China’s consul general in the Japanese city triggering an official complaint from Japan by commenting that “the dirty head that sticks itself out must be cut off”.

China then called in Japan's diplomat for the first occasion since 2023, and Beijing's military authorities stated that any Japanese intervention would be certain to collapse.

Warning for Citizens

Late last week, China advised its people to avoid visiting Japan, leading Japan to request China to take “suitable actions”, though it provided no details.

Three Chinese airlines said on Saturday that flights to Tokyo could be cancelled without penalty.

Adding to the tensions, Beijing's administration on Sunday urged its citizens to “carefully reconsider” studying in Japan, citing what it characterized as an volatile safety situation.

While the advice does not amount to a ban, a significant decrease in the population of learners from China could have a negative impact 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.

Media Response

Late on Saturday, a Chinese state media editorial 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 likely draw in other powers, including the US, and could rapidly escalate to a large-scale conflict with unimaginable consequences.”

Policy Standpoints

The administration in Taipei says the island's residents alone determine their destiny. Officials in Tokyo have traditionally refrained from publicly mentioning Taiwan 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 mainland China is “unavoidable”, and casts any opposition to it as escalatory. As it advances toward potential armed takeover, China has also been increasing its political operations and its statements towards Taiwan.
