China Dispatches Maritime Patrol Vessels to Diaoyu Islands Amid Tensions with Tokyo

Beijing has sent its coast guard into the waters of the Diaoyu islands and unmanned aerial vehicles near outlying Japan's territory as China escalates strains following 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 territorial seas of the Diaoyu islands, which are under the control of Japan but also claimed 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 undertaken by the China coast guard to protect its sovereign claims,” the statement said.

Bilateral Tensions

Beijing and Tokyo have repeatedly faced off 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 Beijing assaults democratically ruled Taiwan it might provoke a armed reaction from Tokyo.

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

Taiwan's Position

China claims the island as its own territory and plans to incorporate it under what it describes as “reunification”. It has not ruled out the military option. Taiwan’s government and people categorically refuse the idea of Beijing's control – 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 risk escalating into a international confrontation, possibly drawing in the US and other partner nations including Japan, which has land just 68 miles from Taiwan.

Military Activity

In Taiwan, the military authorities said on Sunday morning that it had observed 30 Chinese military aircraft, multiple naval vessels and one “official” ship, which was likely the maritime patrol, active near the island over the past 24 hours.

Official charts released 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 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 China had been carrying out another “combined military exercise” to “harass the airspace and sea around us”. It noted Taiwan had dispatched military assets to track the developments. The island documents these operations a few times monthly 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 remarks, with China’s consul general in the Japanese city prompting a formal protest from Japan by stating that “those who interfere will face consequences”.

Beijing then called in Japan's diplomat for the first occasion since 2023, and China’s defence ministry stated that any Tokyo's involvement 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 “appropriate measures”, though it did not elaborate.

Three Chinese airlines announced this weekend that flights to Tokyo 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 described as an unstable security environment.

While the advice does not amount to a ban, a dramatic reduction in the number of Chinese students could have a detrimental effect on academic institutions in Japan. 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.

Media Response

Late on Saturday, a official press commentary charged the Japanese official with performing 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 powers, including the US, and could rapidly escalate to a major confrontation with unimaginable consequences.”

Strategic Positions

The government of Taiwan says only its people can decide its future. Japanese leaders have previously avoided discussing the island openly when addressing potential conflicts, maintaining a “strategic ambiguity” also preferred by Japan's primary defense partner, the United States.

However, 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 the island.
