Beijing Dispatches Coast Guard Vessels to Senkaku Islands Amid Tensions with Tokyo

Beijing has sent its coast guard through the maritime area of the Senkaku islands and unmanned aerial vehicles past outlying Japan's territory as China ramps up strains over the Japan's leader's remarks regarding the island of Taiwan.

Patrol Operations

On Sunday, the China's maritime patrol announced that its vessels carried out a “lawful patrol operation” through the waters of the Senkaku, which are under the control of Japan but also claimed by China.

“Chinese maritime patrol unit 1307 conducted patrols within the maritime jurisdiction of the Diaoyu islands. This was a lawful patrol operation undertaken by the Chinese maritime authorities to protect its sovereign claims,” officials declared.

Diplomatic Spat

Beijing and Tokyo have consistently clashed around the islands but the latest activity come amid an escalating political dispute after the Japanese prime minister, Sanae Takaichi, addressed lawmakers that if China attack the self-governing island of Taiwan it could trigger a armed reaction from Japan.

That sparked an angry response from China, which has indicated it demands a retraction from the Japanese official.

Island's Stance

Beijing asserts the island as its sovereign land and intends to annex it under what it terms “unification”. It has not ruled out the use of force. Taiwan’s government and people overwhelmingly reject the idea of Beijing's control – preferring to maintain the current situation without explicitly declaring themselves independent, but vowing to defend themselves if required.

An attack or invasion by China would risk escalating into a regional or global conflict, possibly drawing in the United States and other allies including Tokyo, which has land just 110km (68 miles) from the island.

Defense Operations

On the island, the military authorities said on Sunday morning that it had detected 30 Chinese military aircraft, multiple naval vessels and one “official” ship, which was likely the maritime patrol, operating around the island over the past 24 hours.

Official charts released showed up to three drones flying between the island and the Japan's territory off its north-east coast, appearing to go unusually near to the nearby Japanese island. Chinese military transits there are not rare, but uncommon, and Chinese military activity in the island's ADIZ generally has been low in recent weeks.

Late on Saturday, the ministry said China had been conducting another “combined military exercise” to “test our defensive capabilities”. It noted the island had sent its own aircraft and ships to monitor the situation. The island documents these operations a few times monthly as part of what the Taiwanese government says is an continuous strategic pressure.

Political Strain

Tokyo has been experiencing increased strain from China since the Japanese official made her comments, with Beijing's diplomatic representative in the Japanese city prompting a formal protest from Tokyo by stating that “the dirty head that sticks itself out must be cut off”.

Beijing then summoned the Japanese ambassador 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

Late last week, Beijing cautioned its citizens against travelling to Japan, prompting Tokyo to urge Beijing to take “appropriate measures”, 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, China’s government on Sunday urged its citizens to “carefully reconsider” studying in Japan, citing what it described as an volatile safety situation.

While the advice does not amount to a ban, a significant decrease in the number of Chinese students could have a detrimental effect on Japanese universities. A record 336,708 foreign nationals were studying in Japan last year, according to official data. They included more than 123,000 Chinese students – by far the single biggest group.

Official Commentary

Earlier this weekend, a Chinese state media editorial accused Takaichi of staging a political stunt that was “both reckless and fundamentally flawed”.

“A clash between Tokyo and Beijing would not be a limited skirmish; it would probably involve other powers, including the United States, and could quickly spiral into a large-scale conflict with severe repercussions.”

Strategic Positions

The administration in Taipei says the island's residents alone determine their destiny. Japanese leaders have traditionally refrained from publicly mentioning Taiwan when discussing such scenarios, maintaining a “deliberate vagueness” 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 casts any opposition to it as escalatory. As it advances toward potential armed takeover, Beijing has also been increasing its political operations and its statements towards Taiwan.
