China Sends Maritime Patrol Vessels to Senkaku Islands Amid Dispute with Tokyo

Beijing has sent its coast guard into the waters of the Diaoyu islands and military drones near outlying Japan's territory as China escalates tensions over the Japan's leader's remarks regarding the island of Taiwan.

Rights Enforcement Activities

On Sunday, the China's maritime patrol stated that its ships conducted a “rights enforcement patrol” through the waters of the Senkaku, which are under the control of Tokyo but also asserted as territory by Beijing.

“Chinese maritime patrol unit 1307 conducted patrols within the territorial waters of the Diaoyu islands. This was a lawful patrol operation undertaken by the Chinese maritime authorities to uphold its rights and interests,” the statement said.

Diplomatic Spat

China and Japan have consistently clashed around the islands but the latest activity occur during an intensifying diplomatic spat after the Japanese prime minister, the Japanese official, addressed lawmakers that if Beijing assaults the self-governing island of Taiwan it might provoke a military response from Japan.

That sparked an angry response from Beijing, which has signalled it expects a withdrawal from the Japanese official.

Taiwan's Position

China claims the island as its sovereign land and intends to annex it under what it terms “unification”. It has left open the military option. Taiwan’s government and people categorically refuse the prospect of Chinese rule – preferring to maintain the status quo without formally announcing independence, but pledging to protect their sovereignty if necessary.

An military assault by Beijing would threaten to spiral into a regional or global conflict, potentially involving the US and other partner nations including Tokyo, which has land just 110km (68 miles) from Taiwan.

Defense Operations

On the island, the military authorities said on Sunday morning that it had observed three dozen PLA planes, multiple naval vessels and one “official” ship, which was probably the coast guard, operating around the island over the past 24 hours.

Maps provided by the ministry showed up to multiple UAVs operating near the island and the Japan's territory off its north-east coast, appearing to go unusually near to Yonaguni. PLA movements there are occasional, but uncommon, and Beijing's defense operations in Taiwan’s air defence identification zone generally has been low in the past month.

Late on Saturday, the ministry said Beijing had been conducting another “combined military exercise” to “harass the airspace and sea around us”. It added Taiwan had sent its own aircraft and ships to track the developments. Taiwan reports such Chinese patrols a few times monthly 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 Tokyo by commenting 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 stated that any Japanese intervention would be doomed to fail.

Warning for Citizens

Late last week, Beijing cautioned its citizens against travelling to Japan, leading Japan to request China to take “suitable actions”, though it did not elaborate.

Three Chinese airlines said on Saturday that tickets to Japan could be cancelled without penalty.

Adding to the tensions, Beijing's administration on the weekend 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 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 studying in Japan last year, according to official data. They featured over 123,000 learners from China – by far the largest demographic.

Official Commentary

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 probably involve other nations, including the United States, and could rapidly escalate to a major confrontation with unimaginable consequences.”

Policy Standpoints

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

However, Beijing's governing party says the incorporation of the island with the mainland China is “unavoidable”, and portrays dissent as provocative. As it advances toward potential armed takeover, Beijing has also been escalating its non-military activity and its rhetoric towards the island.
