China Dispatches Coast Guard Ships to Senkaku Islands Amid Tensions with Japan

Beijing has sent its coast guard into the waters of the Diaoyu islands and military drones past outlying Japan's territory as China escalates tensions following the Japanese prime minister’s comments regarding the island of Taiwan.

Rights Enforcement Activities

On Sunday, the China's maritime patrol stated that its vessels conducted a “lawful patrol operation” through the territorial seas of the Diaoyu islands, which are under the control of Tokyo but also claimed by China.

“China coast guard vessel 1307 formation conducted patrols within the territorial waters of the Diaoyu islands. This was a legitimate rights enforcement activity conducted by the Chinese maritime authorities to uphold its rights and interests,” officials declared.

Diplomatic Spat

China and Japan have consistently clashed around the disputed territory but the latest activity come amid an escalating political dispute after the Japan's leader, Sanae Takaichi, told parliament that if Beijing assaults 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 Takaichi.

Island's Stance

Beijing asserts Taiwan as its own territory and intends to annex it under what it terms “reunification”. It has not ruled out the military option. Taiwan’s government and people overwhelmingly reject the prospect of Chinese rule – preferring to maintain the current situation without formally announcing independence, but vowing to defend themselves if necessary.

An military assault by Beijing would risk escalating into a international confrontation, possibly drawing in the US and other allies including Tokyo, which has land just 110km (68 miles) from Taiwan.

Military Activity

In Taiwan, the military authorities said on Sunday morning that it had detected three dozen PLA planes, seven navy ships and one “official” ship, which was likely the coast guard, operating around the territory over the previous day.

Official charts released showed up to multiple UAVs operating near Taiwan and the Japanese islands off its north-east coast, seeming to travel unusually near to the nearby Japanese island. PLA movements there are not rare, but infrequent, and Beijing's defense operations in the island's ADIZ generally has been minimal in the past month.

Earlier this weekend, the ministry said Beijing had been carrying out another “joint combat patrol” to “test our defensive capabilities”. It noted the island had dispatched military assets to monitor the situation. The island documents these operations a couple of times a month as part of what the Taiwanese government says is an ongoing military pressure campaign.

Diplomatic Pressure

Japan has been facing mounting pressure from China since the Japanese official made her remarks, with Beijing's diplomatic representative in Osaka prompting a formal protest 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 doomed to fail.

Warning for Citizens

Late last week, Beijing advised its people to avoid visiting Japan, leading Japan to request China to take “appropriate measures”, though it did not elaborate.

Three Chinese airlines announced this weekend 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 described as an volatile safety situation.

Although not an outright prohibition, a significant decrease 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 single biggest group.

Official Commentary

Earlier this weekend, a official press commentary 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 United States, and could quickly spiral into a major confrontation with severe repercussions.”

Strategic Positions

The administration in Taipei says only its people can decide its future. Officials in Tokyo have previously avoided discussing the island openly when discussing such scenarios, maintaining a “strategic ambiguity” also favoured by Japan's primary defense partner, the United States.

However, China’s ruling Communist party says the unification of Taiwan with the People’s Republic of China is “inevitable”, and casts any opposition to it as escalatory. As it moves towards being capable of military annexation, China has also been increasing its political operations and its rhetoric towards Taiwan.
