China Sends Coast Guard Ships to Senkaku Islands Amid Tensions with Tokyo

Beijing has deployed its coast guard into the maritime area of the Senkaku islands and unmanned aerial vehicles near outlying Japanese territory as Beijing escalates tensions over the Japan's leader's comments regarding Taiwan.

Rights Enforcement Activities

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

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

Diplomatic Spat

China and Japan have consistently clashed around the disputed territory but the recent developments come amid an intensifying diplomatic spat after the Japan's leader, Sanae Takaichi, addressed lawmakers that if China attack the self-governing island of Taiwan it might provoke a military response from Japan.

That sparked an angry response from China, which has indicated it demands a retraction from Takaichi.

Island's Stance

China claims the island as its own territory and intends to annex it under what it terms “unification”. It has left open the use of force. The island's administration and people categorically refuse the prospect of Chinese rule – choosing to preserve the status quo without formally announcing independence, 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 US and other partner nations including Tokyo, which has land just 68 miles from Taiwan.

Military Activity

On the island, the military authorities said on Sunday morning that it had detected 30 Chinese military aircraft, multiple naval vessels and one government vessel, which was likely the maritime patrol, operating around the territory over the previous day.

Maps provided by the ministry showed up to three drones operating near Taiwan and the Japan's territory off its northeastern shoreline, seeming to travel unusually near to Yonaguni. PLA movements there are occasional, but uncommon, and Chinese military activity in Taiwan’s air defence identification zone generally has been low in recent weeks.

Late on Saturday, the defense officials said Beijing had been carrying out another “combined military exercise” to “harass the airspace and sea around us”. It added Taiwan had dispatched military assets to track the developments. The island documents these operations a few times monthly as part of what the Taiwanese government says is an continuous strategic pressure.

Political Strain

Japan has been facing mounting pressure from China since the Japanese official made her comments, with Beijing's diplomatic representative in the Japanese city triggering an official complaint from Japan by stating that “the dirty head that sticks itself out must be cut off”.

Beijing then called in Japan's diplomat for the first occasion since 2023, and Beijing's military authorities declared that any Japanese intervention would be certain to collapse.

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.

Multiple carriers from China said on Saturday that flights to Tokyo could be refunded or changed for free.

In another escalation, Beijing's administration 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 population of learners from China could have a detrimental effect on Japanese universities. 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 largest demographic.

Media Response

Earlier this weekend, a official press commentary accused Takaichi of staging a political stunt that was “not just dangerously provocative but fundamentally perverse”.

“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 unimaginable consequences.”

Strategic Positions

The administration in Taipei says only its people can decide its future. Officials in Tokyo have previously avoided discussing the island openly when addressing potential conflicts, maintaining a “strategic ambiguity” also preferred by Tokyo’s main security ally, the United States.

However, China’s ruling Communist party says the unification of Taiwan with the People’s Republic of China is “unavoidable”, and portrays dissent as provocative. As it moves towards being capable of military annexation, China has also been increasing its political operations and its statements towards the island.
