Beijing Sends Coast Guard Vessels to Senkaku Islands During Tensions with Japan

China has sent its maritime law enforcement into the maritime area of the Senkaku islands and unmanned aerial vehicles near remote Japan's territory as Beijing escalates tensions following the Japanese prime minister’s comments regarding the island of Taiwan.

Patrol Operations

On Sunday, the China's maritime patrol stated that its vessels conducted a “rights enforcement patrol” through the territorial seas of the Diaoyu islands, which are administered by Tokyo but also asserted as territory by China.

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

Diplomatic Spat

China and Japan have consistently clashed around the islands but the recent developments occur during an intensifying diplomatic spat after the Japan's leader, the Japanese official, told parliament that if China attack democratically ruled Taiwan it could trigger a armed reaction from Japan.

That provoked a furious reaction from China, which has indicated it demands a retraction from Takaichi.

Taiwan's Position

Beijing asserts the island as its own territory and plans to incorporate it under what it describes as “unification”. It has not ruled out the military option. Taiwan’s government and citizens categorically refuse the idea of Beijing's control – choosing to preserve the current situation without explicitly declaring themselves independent, but vowing to defend themselves if required.

An attack or invasion by Beijing would threaten to spiral 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.

Military Activity

In Taiwan, the defence ministry said on Sunday morning that it had detected three dozen PLA planes, multiple naval vessels and one “official” ship, which was likely the maritime patrol, active near the territory over the previous day.

Official charts released showed up to multiple UAVs operating near Taiwan 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 occasional, but infrequent, and Chinese military activity in the island's ADIZ generally has been minimal in recent weeks.

Earlier this weekend, the ministry said Beijing had been conducting another “joint combat patrol” to “harass the airspace and sea around us”. It added Taiwan had sent its own aircraft and ships to track the developments. The island reports such Chinese patrols a few times monthly as part of what Taipei says is an continuous strategic pressure.

Diplomatic Pressure

Japan has been experiencing increased strain from China since the Japanese official made her comments, with Beijing's diplomatic representative in Osaka prompting a formal protest from Tokyo by commenting 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 declared that any Tokyo's involvement would be doomed to fail.

Travel and Education Advisory

On Friday, Beijing cautioned its citizens against travelling to Japan, prompting Tokyo to urge Beijing to take “suitable actions”, though it provided no details.

Multiple carriers from China announced this weekend that tickets to Japan could be refunded or changed for free.

Adding to the tensions, Beijing's administration on Sunday advised students to rethink education plans in Japan, citing what it characterized as an volatile safety situation.

Although not an outright prohibition, a dramatic reduction in the number of Chinese students could have a detrimental effect on Japanese universities. A record 336,708 foreign nationals were enrolled in Japanese schools last year, according to education statistics. 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 political stunt that was “both reckless and fundamentally flawed”.

“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 major confrontation with severe repercussions.”

Policy Standpoints

The government of Taiwan says the island's residents alone determine their destiny. Officials in Tokyo have previously avoided discussing the island openly when discussing such scenarios, maintaining a “deliberate vagueness” also favoured by Tokyo’s main security ally, the United States.

Nevertheless, Beijing's governing party says the incorporation of the island with the mainland China is “unavoidable”, and casts any opposition to it as escalatory. As it moves towards being capable of military annexation, Beijing has also been increasing its political operations and its rhetoric towards the island.
