Beijing Sends Coast Guard Ships to Senkaku Islands Amid Tensions with Japan

China has sent its maritime law enforcement through the waters of the Diaoyu islands and military drones near remote Japan's territory as China escalates tensions following the Japan's leader's remarks regarding the island of Taiwan.

Rights Enforcement Activities

This past Sunday, the China's maritime patrol announced that its vessels carried out a “lawful patrol operation” through the waters of the Diaoyu islands, which are under the control of Tokyo but also claimed by Beijing.

“Chinese maritime patrol unit 1307 conducted patrols within the maritime jurisdiction of the Diaoyu islands. This was a legitimate rights enforcement activity undertaken by the Chinese maritime authorities to uphold its rights and interests,” the statement said.

Bilateral Tensions

China and Japan have repeatedly faced off around the islands but the recent developments occur during an intensifying diplomatic spat after the Japanese prime minister, Sanae Takaichi, addressed lawmakers that if China attack democratically ruled Taiwan it could trigger a military response from Japan.

That provoked a furious reaction from Beijing, which has indicated it demands a withdrawal from Takaichi.

Taiwan's Position

China claims the island as its sovereign land and plans to incorporate it under what it describes as “unification”. It has not ruled out the military option. The island's administration and citizens categorically refuse the prospect of Chinese rule – choosing to preserve the status quo without explicitly declaring themselves independent, but pledging to protect their sovereignty if necessary.

An attack or invasion by China would threaten to spiral into a regional or global conflict, potentially involving the US and other allies including Tokyo, which has territory just 110km (68 miles) from the island.

Military Activity

On the island, the military authorities said on Sunday morning that it had observed 30 Chinese military aircraft, seven navy ships and one government vessel, which was probably the maritime patrol, active near the territory over the past 24 hours.

Official charts released showed up to multiple UAVs flying between Taiwan and the Japanese islands off its northeastern shoreline, appearing to go unusually near to the nearby Japanese island. PLA movements there are not rare, but infrequent, and Chinese military activity in the island's ADIZ generally has been minimal in the past month.

Late on Saturday, the defense officials said China had been carrying out another “joint combat patrol” to “test our defensive capabilities”. It noted Taiwan had dispatched military assets to monitor the situation. Taiwan documents these operations a few times monthly as part of what Taipei says is an ongoing military pressure campaign.

Diplomatic Pressure

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

Beijing then called in Japan's diplomat for the first occasion since 2023, and China’s defence ministry stated that any Tokyo's involvement would be certain to collapse.

Warning for Citizens

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 flights to Tokyo could be cancelled without penalty.

In another escalation, Beijing's administration on Sunday advised students to rethink education plans in Japan, citing what it described as an unstable security environment.

While the advice does not amount to a ban, a dramatic reduction in the number of Chinese students could have a negative impact on academic institutions in Japan. 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 largest demographic.

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 United States, and could rapidly escalate to a major confrontation with unimaginable consequences.”

Strategic Positions

The administration in Taipei says only its people can decide its future. Japanese leaders have traditionally refrained from discussing the island openly when addressing potential conflicts, maintaining a “strategic ambiguity” also preferred by Japan's primary defense partner, the US.

However, China’s ruling Communist party says the unification of Taiwan with the People’s Republic of 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.
