China Sends Maritime Patrol Ships to Senkaku Islands During Dispute with Japan

China has sent its maritime law enforcement through the maritime area of the Diaoyu islands and military drones past remote Japan's territory as China ramps up strains over the Japan's leader's remarks regarding Taiwan.

Patrol Operations

On Sunday, the Chinese coast guard stated that its ships carried out 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 territorial waters of the Senkaku islands. This was a lawful patrol operation undertaken 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 escalating political dispute after the Japan's leader, Sanae Takaichi, told parliament that if China attack the self-governing island of Taiwan it could trigger a armed reaction from Tokyo.

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

Taiwan's Position

Beijing asserts the island as its own territory and intends to annex it under what it describes as “reunification”. 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 required.

An attack or invasion by China would risk escalating into a international confrontation, possibly drawing in the United States and other allies including Tokyo, which has territory just 110km (68 miles) from Taiwan.

Military Activity

On the island, the military authorities said on Sunday morning that it had observed 30 Chinese military aircraft, seven navy ships and one “official” ship, which was likely the maritime patrol, operating around the territory over the previous day.

Official charts released showed up to three drones operating near Taiwan and the Japanese islands off its northeastern shoreline, seeming to travel particularly close to the nearby Japanese island. PLA movements there are not rare, but infrequent, and Chinese military activity in Taiwan’s air defence identification zone generally has been minimal in the past month.

Earlier this weekend, the ministry said Beijing had been conducting another “joint combat patrol” to “test our defensive capabilities”. It added the island had dispatched military assets to track the developments. Taiwan documents these operations a couple of times a month as part of what the Taiwanese government says is an continuous strategic pressure.

Diplomatic Pressure

Japan has been experiencing increased strain from Beijing since Takaichi made her comments, with China’s consul general in Osaka prompting a formal protest from Japan 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 Beijing's military authorities declared that any Japanese intervention would be certain to collapse.

Warning for Citizens

On Friday, Beijing advised its people to avoid visiting Japan, prompting Tokyo to urge Beijing to take “appropriate measures”, though it did not elaborate.

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

In another escalation, China’s government on the weekend 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 negative impact 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.

Media Response

Earlier this weekend, a official press commentary 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 nations, including the United States, and could quickly spiral into a large-scale conflict with severe repercussions.”

Policy Standpoints

The government of Taiwan says only its people can decide its future. Japanese leaders have previously avoided publicly mentioning Taiwan when addressing potential conflicts, maintaining a “deliberate vagueness” also favoured by Tokyo’s main security ally, the US.

Nevertheless, China’s ruling Communist 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 rhetoric towards the island.
