China Dispatches Coast Guard Vessels to Senkaku Islands During Tensions with Japan

Beijing has sent its coast guard into the waters of the Diaoyu islands and unmanned aerial vehicles near outlying Japan's territory as Beijing escalates tensions over 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 ships 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 performed surveillance within the territorial waters of the Senkaku islands. This was a legitimate rights enforcement activity conducted by the China coast guard to protect its sovereign claims,” officials declared.

Diplomatic Spat

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 Beijing assaults the self-governing island of Taiwan it might provoke a armed reaction from Japan.

That provoked a furious reaction from China, which has signalled it expects a retraction from Takaichi.

Taiwan's Position

Beijing asserts Taiwan as its own territory and intends to annex it under what it terms “unification”. It has not ruled out the military option. The island's administration and citizens overwhelmingly reject the prospect of Chinese rule – preferring to maintain the current situation without explicitly declaring themselves independent, but vowing to defend themselves if necessary.

An attack or invasion by China would risk escalating 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.

Military Activity

In Taiwan, the defence ministry reported this weekend that it had detected 30 Chinese military aircraft, multiple naval vessels and one government vessel, which was probably the maritime patrol, active near the island over the past 24 hours.

Official charts released showed up to three drones operating near the island and the Japan's territory off its northeastern shoreline, 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 defense officials said Beijing had been conducting 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. The island documents these operations a few times monthly as part of what the Taiwanese government says is an continuous strategic pressure.

Diplomatic Pressure

Tokyo has been experiencing increased strain from China since Takaichi 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 Beijing's military authorities declared that any Japanese intervention would be certain to collapse.

Warning for Citizens

On Friday, China cautioned its citizens against travelling to Japan, leading Japan to request China to take “appropriate measures”, though it did not elaborate.

Three Chinese airlines said on Saturday 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 volatile safety situation.

While the advice does not amount to a ban, a significant decrease in the population of learners from China could have a detrimental effect on academic institutions in Japan. A record 336,708 foreign nationals were enrolled in Japanese schools last year, according to official data. They featured over 123,000 learners from China – by far the single biggest group.

Official Commentary

Earlier this weekend, a Chinese state media editorial charged the Japanese official with performing a diplomatic maneuver 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 US, and could rapidly escalate to a major confrontation with unimaginable consequences.”

Policy Standpoints

The administration in Taipei says the island's residents alone determine their destiny. Officials in Tokyo have traditionally refrained from discussing the island openly when addressing potential conflicts, maintaining a “deliberate vagueness” also favoured by Tokyo’s main security ally, the United States.

Nevertheless, Beijing's governing party says the unification of Taiwan with the People’s Republic of China is “inevitable”, and portrays dissent as provocative. As it moves towards being capable of military annexation, Beijing has also been escalating its non-military activity and its rhetoric towards the island.
