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

China has sent its coast guard into the maritime area of the Diaoyu islands and unmanned aerial vehicles past remote Japan's territory as Beijing escalates strains over the Japanese prime minister’s remarks regarding the island of Taiwan.

Patrol Operations

This past Sunday, the Chinese coast guard stated that its ships carried out a “rights enforcement patrol” through the waters of the Diaoyu islands, which are under the control of Tokyo but also claimed by Beijing.

“Chinese maritime patrol unit 1307 conducted patrols within the territorial waters of the Senkaku islands. This was a legitimate rights enforcement activity conducted by the Chinese maritime authorities to uphold its rights and interests,” officials declared.

Diplomatic Spat

China and Japan have consistently clashed around the disputed territory but the latest activity come amid an intensifying diplomatic spat after the Japan's leader, the Japanese official, addressed lawmakers that if Beijing assaults democratically ruled Taiwan it could trigger a military response from Japan.

That sparked an angry response from Beijing, which has indicated it demands a retraction from the Japanese official.

Island's Stance

China claims Taiwan as its own territory and plans to incorporate it under what it terms “reunification”. It has not ruled out the use of force. The island's administration and citizens overwhelmingly reject the prospect of Chinese rule – choosing to preserve the status quo without formally announcing independence, but pledging to protect their sovereignty if necessary.

An attack or invasion by Beijing would threaten to spiral into a international confrontation, potentially involving the United States and other allies including Tokyo, which has land just 110km (68 miles) from the island.

Defense Operations

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 coast guard, active near the territory over the past 24 hours.

Official charts released showed up to multiple UAVs flying between Taiwan and the Japanese islands off its northeastern shoreline, seeming to travel particularly close to Yonaguni. PLA movements there are occasional, but uncommon, and Chinese military activity in Taiwan’s air defence identification zone generally has been minimal in recent weeks.

Late on Saturday, the ministry said Beijing had been carrying out another “combined military exercise” to “harass the airspace and sea around us”. It added the island had sent its own aircraft and ships to monitor the situation. The island documents these operations a couple of times a month as part of what Taipei says is an continuous strategic pressure.

Political Strain

Japan has been experiencing increased strain from Beijing since Takaichi made her comments, 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 called in Japan's diplomat for the first occasion since 2023, and China’s defence ministry stated that any Japanese intervention would be doomed to fail.

Warning for Citizens

Late last week, Beijing advised its people to avoid visiting Japan, prompting Tokyo to urge Beijing to take “appropriate measures”, though it provided no details.

Multiple carriers from China said on Saturday that flights to Tokyo could be cancelled without penalty.

In another escalation, China’s government on the weekend advised students to rethink education plans in Japan, citing what it described as an unstable security environment.

While the advice does not amount to a ban, a significant decrease in the number of Chinese students could have a negative impact on academic institutions in Japan. A historic high of over 336,000 international students were studying in Japan last year, according to official data. They included more than 123,000 Chinese students – by far the single biggest group.

Official Commentary

Earlier this weekend, a Chinese state media editorial accused Takaichi of staging a diplomatic maneuver that was “both reckless and fundamentally flawed”.

“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 rapidly escalate to a major confrontation with unimaginable consequences.”

Policy Standpoints

The government of Taiwan says the island's residents alone determine their destiny. Japanese leaders have traditionally refrained from publicly mentioning Taiwan when addressing potential conflicts, maintaining a “strategic ambiguity” also favoured by Japan's primary defense partner, the US.

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