China Sends Maritime Patrol Ships to Senkaku Islands Amid Dispute with Japan

Beijing has deployed its coast guard through the maritime area of the Senkaku islands and military drones near outlying Japanese territory as Beijing escalates strains over the Japan's leader's comments regarding the island of Taiwan.

Patrol Operations

On Sunday, the Chinese coast guard announced that its ships conducted a “rights enforcement patrol” through the territorial seas of the Diaoyu islands, which are under the control of Japan but also asserted as territory by Beijing.

“Chinese maritime patrol unit 1307 conducted patrols within the territorial waters of the Diaoyu islands. This was a lawful patrol operation conducted by the China coast guard to uphold its rights and interests,” officials declared.

Bilateral Tensions

Beijing and Tokyo have consistently clashed around the disputed territory but the recent developments come amid an intensifying diplomatic spat after the Japanese prime minister, Sanae Takaichi, told parliament that if China attack democratically ruled Taiwan it might provoke a armed reaction from Tokyo.

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

Island's Stance

Beijing asserts Taiwan as its own territory and plans to incorporate it under what it terms “reunification”. It has not ruled out the use of force. Taiwan’s government and people overwhelmingly reject the prospect of Chinese rule – preferring to maintain the current situation without explicitly declaring themselves independent, but pledging to protect their sovereignty if necessary.

An military assault by China would risk escalating into a regional or global conflict, potentially involving the United States and other partner nations including Japan, which has land just 68 miles from the island.

Defense Operations

In Taiwan, the military authorities said on Sunday morning that it had observed three dozen PLA planes, multiple naval vessels and one “official” ship, which was probably the maritime patrol, active near the territory over the past 24 hours.

Official charts released showed up to three drones flying between the island and the Japanese islands off its north-east coast, seeming to travel unusually near to Yonaguni. Chinese military transits there are not rare, but uncommon, and Beijing's defense operations in the island's ADIZ generally has been low in the past month.

Late on Saturday, the ministry said China had been conducting another “joint combat patrol” 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 Taipei says is an continuous strategic pressure.

Diplomatic Pressure

Tokyo has been experiencing increased strain from China since Takaichi made her comments, with Beijing's diplomatic representative in the Japanese city prompting a formal protest 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 China’s defence ministry stated that any Japanese intervention would be doomed to fail.

Travel and Education Advisory

On Friday, Beijing cautioned its citizens against travelling to 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.

Adding to the tensions, Beijing's administration on the weekend advised students to rethink education plans in Japan, citing what it described 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 studying in Japan last year, according to official data. 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 political stunt that was “not just dangerously provocative but fundamentally perverse”.

“A clash between Tokyo and Beijing would not be a small-scale encounter; it would probably involve other nations, including the US, and could quickly spiral into a large-scale conflict with unimaginable consequences.”

Strategic Positions

The government of Taiwan says the island's residents alone determine their destiny. Officials in Tokyo have traditionally refrained from discussing the island openly when discussing such scenarios, maintaining a “strategic ambiguity” also preferred by Japan's primary defense partner, the US.

Nevertheless, China’s ruling Communist party says the incorporation of the island with the mainland China is “inevitable”, and portrays dissent as provocative. As it moves towards being capable of military annexation, Beijing has also been increasing its political operations and its rhetoric towards Taiwan.
