China has deployed its coast guard into the waters of the Diaoyu islands and unmanned aerial vehicles past remote Japanese territory as Beijing ramps up strains over the Japanese prime minister’s comments regarding the island of Taiwan.

Patrol Operations

On Sunday, the China's maritime patrol announced that its ships carried out a “rights enforcement patrol” through the territorial seas of the Diaoyu islands, which are under the control of Japan but also claimed by Beijing.

“Chinese maritime patrol unit 1307 conducted patrols within the territorial waters of the Diaoyu islands. This was a legitimate rights enforcement activity conducted by the Chinese maritime authorities to protect its sovereign claims,” the statement said.

Bilateral Tensions

China and Japan have repeatedly faced off around the islands but the latest activity occur during an intensifying diplomatic spat after the Japanese prime minister, the Japanese official, told parliament that if Beijing assaults 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.

Taiwan's Position

China claims Taiwan as its sovereign land and plans to incorporate it under what it describes as “reunification”. It has not ruled out the use of force. The island's administration and citizens overwhelmingly reject the prospect of Chinese rule – choosing to preserve the status quo without formally announcing independence, but pledging to protect their sovereignty if necessary.

An attack or invasion by China would risk escalating into a international confrontation, possibly drawing in the US and other allies including Japan, which has land just 110km (68 miles) from the island.

Military Activity

In Taiwan, 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 coast guard, active near the island over the past 24 hours.

Official charts released showed up to three drones flying between the island and the Japanese islands off its northeastern shoreline, appearing to go unusually near to Yonaguni. PLA movements there are not rare, but uncommon, and Beijing's defense operations in Taiwan’s air defence identification zone generally has been low in the past month.

Earlier this weekend, the defense officials said Beijing had been conducting another “joint combat patrol” to “test our defensive capabilities”. It added Taiwan had dispatched military assets to monitor the situation. The island documents these operations a few times monthly as part of what the Taiwanese government says is an ongoing military pressure campaign.

Diplomatic Pressure

Japan has been facing mounting pressure from China since the Japanese official made her comments, with China’s consul general in the Japanese city prompting a formal protest from Tokyo by commenting that “those who interfere will face consequences”.

Beijing then summoned the Japanese ambassador for the first occasion since 2023, and Beijing's military authorities stated that any Japanese intervention would be certain to collapse.

Warning for Citizens

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

Three Chinese airlines said on Saturday that tickets to Japan could be cancelled without penalty.

Adding to the tensions, China’s government on the weekend 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 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.

Official Commentary

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 limited skirmish; it would likely draw in other nations, including the US, and could rapidly escalate to a major confrontation with severe repercussions.”

Policy Standpoints

The government of Taiwan says only its people can decide its future. Officials in Tokyo have previously avoided publicly mentioning Taiwan when discussing such scenarios, maintaining a “strategic ambiguity” also preferred by Japan's primary defense partner, the United States.

Nevertheless, Beijing's governing party says the unification of Taiwan with the mainland China is “inevitable”, and portrays dissent as provocative. As it moves towards being capable of military annexation, Beijing has also been escalating its non-military activity and its statements towards the island.
