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

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

Rights Enforcement Activities

On Sunday, the China's maritime patrol stated that its vessels carried out a “rights enforcement patrol” through the territorial seas of the Senkaku, which are administered by Japan but also claimed by Beijing.

“China coast guard vessel 1307 formation conducted patrols within the territorial waters of the Senkaku 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 repeatedly faced off around the islands but the latest activity come amid an escalating political dispute after the Japanese prime minister, 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 Beijing, which has signalled it expects a withdrawal from the Japanese official.

Taiwan's Position

Beijing asserts Taiwan as its own territory and plans to incorporate it under what it terms “unification”. It has left open the use of force. Taiwan’s government and citizens categorically refuse the idea of Beijing's control – choosing to preserve the status quo without formally announcing independence, but vowing to defend themselves if required.

An attack or invasion by Beijing would threaten to spiral into a international confrontation, possibly drawing in the US and other allies including Japan, which has territory just 68 miles from Taiwan.

Military Activity

On the island, the defence ministry said on Sunday morning that it had observed 30 Chinese military aircraft, seven navy ships and one “official” ship, which was likely the coast guard, active near the territory over the previous day.

Official charts released showed up to three drones flying between the island and the Japanese islands off its northeastern shoreline, seeming to travel particularly close to Yonaguni. PLA movements there are not rare, but uncommon, and Beijing's defense operations in the island's ADIZ generally has been minimal in the past month.

Earlier this weekend, the ministry said China had been carrying out another “joint combat patrol” to “harass the airspace and sea around us”. It added Taiwan had dispatched military assets 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.

Diplomatic Pressure

Tokyo has been facing mounting pressure from China since Takaichi made her remarks, with Beijing's diplomatic representative in the Japanese city triggering an official complaint from Tokyo by stating that “those who interfere will face consequences”.

Beijing then called in Japan's diplomat for the first occasion since 2023, and Beijing's military authorities declared 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 said on Saturday that tickets to Japan could be cancelled without penalty.

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

Although not an outright prohibition, a dramatic reduction 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 education statistics. They included more than 123,000 Chinese students – 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 small-scale encounter; it would likely draw in other nations, including the US, and could rapidly escalate to a major confrontation with severe repercussions.”

Strategic Positions

The government of Taiwan says only its people can decide its future. Officials in Tokyo have traditionally refrained from discussing the island openly when addressing potential conflicts, maintaining a “strategic ambiguity” also favoured 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 casts any opposition to it as escalatory. As it moves towards being capable of military annexation, Beijing has also been increasing its political operations and its rhetoric towards Taiwan.
