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

China has sent its coast guard into the maritime area of the Diaoyu islands and unmanned aerial vehicles near remote Japan's territory as Beijing ramps up strains over the Japan's leader's comments regarding the island of Taiwan.

Patrol Operations

On Sunday, the Chinese coast guard announced that its vessels carried out a “rights enforcement patrol” through the waters of the Senkaku, which are under the control of Japan but also claimed by Beijing.

“Chinese maritime patrol unit 1307 conducted patrols 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

China and Japan have consistently clashed around the islands but the recent developments come amid an escalating political dispute after the Japan's leader, the Japanese official, told parliament that if China attack the self-governing island of Taiwan it could trigger a armed reaction from Tokyo.

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

Taiwan's Position

China claims the island as its own territory and plans to incorporate it under what it describes as “unification”. It has not ruled out the use of force. Taiwan’s government and citizens overwhelmingly reject the idea of Beijing's control – preferring to maintain the status quo without formally announcing independence, but pledging to protect their sovereignty if necessary.

An attack or invasion by China would threaten to spiral into a international confrontation, potentially involving the United States and other partner nations including Tokyo, which has territory just 110km (68 miles) from the island.

Defense Operations

In Taiwan, the military authorities reported this weekend that it had observed 30 Chinese military aircraft, multiple naval vessels and one “official” ship, which was likely the coast guard, active near the territory over the past 24 hours.

Maps provided by the ministry showed up to three drones operating near the island and the Japanese islands off its north-east coast, appearing to go unusually near to Yonaguni. Chinese military transits there are not rare, but uncommon, and Chinese military activity in Taiwan’s air defence identification zone generally has been minimal in the past month.

Late on Saturday, the defense officials said China had been carrying out 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. Taiwan documents these operations a couple of times a month as part of what Taipei says is an continuous strategic pressure.

Diplomatic Pressure

Japan has been facing mounting pressure from China since Takaichi made her remarks, with Beijing's diplomatic representative in Osaka prompting a formal protest from Tokyo 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 Tokyo's involvement would be doomed to fail.

Travel and Education Advisory

On Friday, China advised its people to avoid visiting Japan, leading Japan to request China to take “suitable actions”, though it did not elaborate.

Multiple carriers from China announced this weekend that tickets to Japan could be cancelled without penalty.

In another escalation, Beijing's administration on Sunday 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 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 included more than 123,000 Chinese students – by far the single biggest group.

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 small-scale encounter; it would likely draw in other nations, including the United States, and could quickly spiral into a large-scale conflict with severe repercussions.”

Policy Standpoints

The government of Taiwan says only its people can decide its future. Officials in Tokyo have previously avoided publicly mentioning Taiwan when addressing potential conflicts, maintaining a “strategic ambiguity” also favoured by Tokyo’s main security ally, the United States.

Nevertheless, 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 increasing its political operations and its statements towards the island.
