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

Beijing has deployed its maritime law enforcement into the maritime area of the Diaoyu islands and military drones past outlying Japan's territory as Beijing ramps up strains following the Japan's leader's remarks regarding Taiwan.

Rights Enforcement Activities

On Sunday, the Chinese coast guard stated that its vessels conducted a “rights enforcement patrol” through the territorial seas of the Diaoyu islands, which are under the control of Japan but also asserted as territory by China.

“China coast guard vessel 1307 formation performed surveillance within the maritime jurisdiction of the Diaoyu islands. This was a legitimate rights enforcement activity conducted by the Chinese maritime authorities to uphold its rights and interests,” officials declared.

Bilateral Tensions

Beijing and Tokyo have repeatedly faced off around the islands but the latest activity come amid 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 provoked a furious reaction from Beijing, which has indicated it demands a withdrawal from Takaichi.

Island's Stance

Beijing asserts 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 categorically refuse the prospect of Chinese rule – choosing to preserve the current situation without formally announcing independence, but vowing to defend themselves if required.

An military assault by Beijing would threaten to spiral into a international confrontation, possibly drawing in the United States and other partner nations including Japan, which has territory 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, seven navy ships and one “official” ship, which was likely the coast guard, operating around the territory over the previous day.

Maps provided by the ministry showed up to three drones flying between the island and the Japan's territory off its northeastern shoreline, seeming to travel particularly close to Yonaguni. PLA movements there are not rare, but uncommon, and Chinese military activity in Taiwan’s air defence identification zone generally has been low in the past month.

Late on Saturday, the defense officials said Beijing had been carrying out another “combined military exercise” to “test our defensive capabilities”. It noted the island had dispatched military assets to track the developments. Taiwan reports such Chinese patrols a couple of times a month as part of what the Taiwanese government says is an continuous strategic pressure.

Diplomatic Pressure

Tokyo has been experiencing increased strain from Beijing since Takaichi made her remarks, with China’s consul general in the Japanese city triggering an official complaint from Japan by stating that “those who interfere will face consequences”.

Beijing then summoned the Japanese ambassador for the first occasion since 2023, and China’s defence ministry declared that any Tokyo's involvement would be certain to collapse.

Warning for Citizens

On Friday, Beijing advised its people to avoid visiting Japan, leading Japan to request China to take “appropriate measures”, though it did not elaborate.

Three Chinese airlines said on Saturday that tickets to Japan 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.

Although not an outright prohibition, a dramatic reduction in the population of learners from China 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 featured over 123,000 learners from China – by far the single biggest group.

Media Response

Earlier this weekend, a official press commentary accused Takaichi of staging a political stunt that was “both reckless and fundamentally flawed”.

“A conflict between Japan and China would not be a limited skirmish; it would likely draw in other nations, including the US, and could rapidly escalate to a major confrontation with unimaginable consequences.”

Strategic Positions

The administration in Taipei says the island's residents alone determine their destiny. Officials in Tokyo have traditionally refrained from publicly mentioning Taiwan when addressing potential conflicts, maintaining a “strategic ambiguity” also favoured by Tokyo’s main security ally, the United States.

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