China Sends Coast Guard Ships to Senkaku Islands Amid Dispute with Japan

Beijing has sent its coast guard into the maritime area of the Senkaku islands and military drones past outlying Japanese territory as Beijing escalates strains over the Japanese prime minister’s comments regarding Taiwan.

Patrol Operations

On Sunday, the China's maritime patrol stated that its ships carried out a “rights enforcement patrol” through the territorial seas of the Senkaku, which are administered by Japan but also claimed by China.

“China coast guard vessel 1307 formation conducted patrols within the maritime jurisdiction of the Senkaku islands. This was a legitimate rights enforcement activity conducted by the China coast guard to protect its sovereign claims,” officials declared.

Diplomatic Spat

China and Japan have repeatedly faced off around the islands but the latest activity occur during an escalating political dispute after the Japanese prime minister, Sanae Takaichi, told parliament that if China attack democratically ruled Taiwan it could trigger a armed reaction from Tokyo.

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

Island's Stance

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 overwhelmingly reject 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 Beijing would risk escalating into a regional or global conflict, possibly drawing in the United States and other partner nations including Japan, which has territory just 68 miles from Taiwan.

Military Activity

In Taiwan, the military authorities reported this weekend that it had observed 30 Chinese military aircraft, seven navy ships and one “official” ship, which was probably 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 Yonaguni. PLA movements there are not rare, but uncommon, and Beijing's defense operations in the island's ADIZ generally has been minimal in recent weeks.

Late on Saturday, the ministry said China had been conducting another “combined military exercise” to “test our defensive capabilities”. It added Taiwan had dispatched military assets to monitor the situation. The island documents these operations a couple of times a month as part of what Taipei says is an ongoing military pressure campaign.

Diplomatic Pressure

Japan has been experiencing increased strain from Beijing since Takaichi made her comments, with Beijing's diplomatic representative in Osaka prompting a formal protest from Tokyo by commenting that “those who interfere will face consequences”.

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

Travel and Education Advisory

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

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

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.

Although not an outright prohibition, a dramatic reduction in the population of learners from China could have a detrimental effect on Japanese universities. A historic high of over 336,000 international students were enrolled in Japanese schools last year, according to education statistics. They featured over 123,000 learners from China – by far the largest demographic.

Official Commentary

Late on Saturday, a Chinese state media editorial accused Takaichi of staging a political stunt that was “both reckless and fundamentally flawed”.

“A clash between Tokyo and Beijing would not be a small-scale encounter; it would likely draw in other nations, including the United States, and could rapidly escalate to a major confrontation with severe repercussions.”

Policy Standpoints

The administration in Taipei says the island's residents alone determine their destiny. Japanese leaders have previously avoided publicly mentioning Taiwan when discussing such scenarios, maintaining a “strategic ambiguity” also favoured by Japan's primary defense partner, the United States.

Nevertheless, China’s ruling Communist party says the incorporation of the island with the People’s Republic of China is “inevitable”, and portrays dissent as provocative. As it advances toward potential armed takeover, China has also been increasing its political operations and its rhetoric towards Taiwan.
