China Sends Coast Guard Ships to Senkaku Islands During Tensions with Tokyo

Beijing has deployed its maritime law enforcement into the waters of the Diaoyu islands and military drones near outlying Japanese territory as Beijing escalates strains following the Japan's leader's comments regarding Taiwan.

Patrol Operations

On Sunday, the Chinese coast guard stated that its ships conducted a “lawful patrol operation” through the waters of the Senkaku, which are administered by Tokyo but also claimed by China.

“Chinese maritime patrol unit 1307 performed surveillance within the maritime jurisdiction of the Senkaku islands. This was a legitimate rights enforcement activity conducted by the Chinese maritime authorities to protect its sovereign claims,” officials declared.

Diplomatic Spat

Beijing and Tokyo have repeatedly faced off around the islands but the recent developments 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 could trigger a military response from Japan.

That provoked a furious reaction from China, which has signalled it expects a withdrawal from the Japanese official.

Taiwan's Position

China claims the island as its own territory and intends to annex it under what it describes as “unification”. It has not ruled out the military option. The island's administration and citizens categorically refuse the prospect of Chinese rule – choosing to preserve the status quo without explicitly declaring themselves independent, but vowing to defend themselves if necessary.

An military assault by Beijing would threaten to spiral into a international confrontation, possibly drawing in the United States and other allies including Tokyo, which has land just 68 miles from Taiwan.

Defense Operations

On the island, the military authorities reported this weekend that it had observed three dozen PLA planes, seven navy ships and one “official” ship, which was likely the maritime patrol, operating around the island over the previous day.

Official charts released showed up to multiple UAVs flying between the island and the Japanese islands off its northeastern shoreline, appearing to go unusually near to Yonaguni. Chinese military transits there are not rare, but uncommon, and Chinese military activity in Taiwan’s air defence identification zone generally has been minimal in recent weeks.

Late on Saturday, the defense officials said Beijing had been carrying out another “combined military exercise” to “harass the airspace and sea around us”. It added Taiwan had sent its own aircraft and ships to monitor the situation. Taiwan reports such Chinese patrols a couple of times a month as part of what the Taiwanese government says is an ongoing military pressure campaign.

Diplomatic Pressure

Tokyo has been experiencing increased strain from Beijing since Takaichi made her remarks, with China’s consul general in the Japanese city triggering an official complaint from Tokyo by stating that “the dirty head that sticks itself out must be cut off”.

China then summoned the Japanese ambassador for the first occasion since 2023, and China’s defence ministry stated that any Japanese intervention would be certain to collapse.

Warning for Citizens

Late last week, China advised its people to avoid visiting Japan, leading Japan to request China to take “suitable actions”, though it provided no details.

Three Chinese airlines said on Saturday that tickets to Japan could be refunded or changed for free.

In another escalation, Beijing's administration on the weekend urged its citizens to “carefully reconsider” studying 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 negative impact on Japanese universities. A historic high of over 336,000 international students were enrolled in Japanese schools last year, according to official data. They included more than 123,000 Chinese students – by far the single biggest group.

Media Response

Earlier this weekend, a Chinese state media editorial accused Takaichi of staging a diplomatic maneuver that was “not just dangerously provocative but fundamentally perverse”.

“A clash between Tokyo and Beijing would not be a limited skirmish; it would likely draw in other powers, including the United States, and could quickly spiral into a major confrontation with unimaginable consequences.”

Strategic Positions

The government of Taiwan says only its people can decide its future. Officials in Tokyo have traditionally refrained from discussing the island openly when discussing such scenarios, maintaining a “deliberate vagueness” also favoured by Tokyo’s main security ally, the United States.

However, Beijing's governing party says the incorporation of the island with the People’s Republic of China is “unavoidable”, 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 statements towards Taiwan.
