China Dispatches Maritime Patrol Vessels to Senkaku Islands Amid Tensions with Japan

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

Rights Enforcement Activities

On Sunday, the China's maritime patrol announced that its vessels conducted a “lawful patrol operation” through the territorial seas of the Senkaku, which are under the control of Tokyo but also asserted as territory by Beijing.

“China coast guard vessel 1307 formation performed surveillance within the territorial waters of the Senkaku islands. This was a legitimate rights enforcement activity undertaken by the China coast guard to uphold its rights and interests,” officials declared.

Bilateral Tensions

China and Japan have consistently clashed around the disputed territory but the recent developments occur during an escalating political dispute after the Japanese prime minister, Sanae Takaichi, told parliament that if Beijing assaults democratically ruled Taiwan it might provoke a military response from Japan.

That sparked an angry response from Beijing, which has signalled it expects a retraction from Takaichi.

Island's Stance

China claims Taiwan as its own territory and plans to incorporate it under what it terms “reunification”. It has left open the military option. The island's administration and citizens overwhelmingly reject the prospect of Chinese rule – preferring to maintain the status quo without explicitly declaring themselves independent, but vowing to defend themselves if necessary.

An military assault by China would risk escalating into a regional or global conflict, potentially involving the US and other partner nations including Tokyo, which has territory just 110km (68 miles) from the island.

Military Activity

In Taiwan, the defence ministry reported this weekend that it had detected 30 Chinese military aircraft, seven navy ships and one “official” ship, which was probably the maritime patrol, active near the territory over the past 24 hours.

Official charts released showed up to multiple UAVs operating near the island and the Japan's territory off its northeastern shoreline, appearing to go particularly close to Yonaguni. Chinese military transits there are occasional, but uncommon, 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 “combined military exercise” to “harass the airspace and sea around us”. It noted Taiwan had sent its own aircraft and ships to track the developments. Taiwan 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 facing mounting pressure from China since the Japanese official made her remarks, with China’s consul general in the Japanese city 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 China’s defence ministry declared that any Japanese intervention would be doomed to fail.

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 did not elaborate.

Three Chinese airlines announced this weekend that flights to Tokyo could be cancelled without penalty.

In another escalation, China’s government on Sunday advised students to rethink education plans in Japan, citing what it characterized as an volatile safety situation.

While the advice does not amount to a ban, a significant decrease 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 included more than 123,000 Chinese students – by far the largest demographic.

Official Commentary

Late on Saturday, a official press commentary accused Takaichi of staging a political stunt that was “not just dangerously provocative but fundamentally perverse”.

“A conflict between Japan and China would not be a small-scale encounter; it would likely draw in other powers, including the US, 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. Officials in Tokyo have traditionally refrained from discussing the island openly when addressing potential conflicts, maintaining a “strategic ambiguity” also preferred by Tokyo’s main security ally, the US.

Nevertheless, Beijing's governing party says the unification of Taiwan with the People’s Republic of China is “unavoidable”, and casts any opposition to it as escalatory. As it advances toward potential armed takeover, China has also been increasing its political operations and its rhetoric towards the island.
