Beijing has deployed its coast guard through the waters of the Diaoyu islands and military drones past outlying Japanese territory as Beijing escalates strains over the Japanese prime minister’s comments regarding Taiwan.

Rights Enforcement Activities

This past Sunday, the Chinese coast guard stated that its vessels conducted a “lawful patrol operation” through the territorial seas of the Diaoyu islands, which are under the control of Tokyo but also asserted as territory by China.

“China coast guard vessel 1307 formation conducted patrols within the territorial waters of the Diaoyu islands. This was a lawful patrol operation 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 disputed territory but the recent developments occur during an escalating political dispute after the Japanese prime minister, the Japanese official, told parliament that if Beijing assaults the self-governing island of Taiwan it might provoke a military response from Tokyo.

That sparked an angry response from Beijing, which has signalled it expects a withdrawal from Takaichi.

Island's Stance

China claims Taiwan as its sovereign land and intends to annex it under what it terms “reunification”. It has not ruled out the use of force. The island's administration and citizens categorically refuse the prospect of Chinese rule – choosing to preserve the status quo without explicitly declaring themselves independent, but pledging to protect their sovereignty if necessary.

An military assault by Beijing would threaten to spiral into a regional or global conflict, possibly drawing in the United States and other partner nations including Tokyo, which has territory just 110km (68 miles) from the island.

Military Activity

In Taiwan, the defence ministry said on Sunday morning that it had detected three dozen PLA planes, seven navy ships and one “official” ship, which was probably the maritime patrol, active near the island over the past 24 hours.

Maps provided by the ministry showed up to multiple UAVs operating near Taiwan and the Japanese islands off its north-east coast, seeming to travel unusually near to Yonaguni. Chinese military transits there are occasional, but uncommon, and Chinese military activity in the island's ADIZ generally has been low in recent weeks.

Late on Saturday, the ministry said Beijing had been conducting another “combined military exercise” to “test our defensive capabilities”. It added the island had dispatched military assets to track the developments. The island reports such Chinese patrols a few times monthly as part of what Taipei says is an continuous strategic pressure.

Political Strain

Japan has been facing mounting pressure from Beijing since Takaichi made her remarks, with Beijing's diplomatic representative in Osaka triggering an official complaint from Japan by stating that “those who interfere will face consequences”.

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

Travel and Education Advisory

Late last week, China cautioned its citizens against travelling to Japan, leading Japan to request China to take “appropriate measures”, though it provided no details.

Three Chinese airlines announced this weekend that flights to Tokyo could be cancelled without penalty.

In another escalation, China’s government on Sunday urged its citizens to “carefully reconsider” studying in Japan, citing what it described as an unstable security environment.

While the advice does not amount to a ban, a significant decrease in the number of Chinese students could have a detrimental effect on academic institutions in Japan. A historic high of over 336,000 international students were studying in Japan last year, according to education statistics. They included more than 123,000 Chinese students – by far the single biggest group.

Media Response

Earlier this weekend, a Chinese state media editorial charged the Japanese official with performing a diplomatic maneuver that was “both reckless and fundamentally flawed”.

“A conflict between Japan and China would not be a small-scale encounter; it would probably involve other nations, including the United States, and could rapidly escalate to a major confrontation with severe repercussions.”

Policy Standpoints

The administration in Taipei says only its people can decide its future. Officials in Tokyo have traditionally refrained from discussing the island openly when discussing such scenarios, maintaining a “deliberate vagueness” also favoured by Japan's primary defense partner, the US.

However, China’s ruling Communist party says the incorporation of the island with the People’s Republic of China is “unavoidable”, and casts any opposition to it as escalatory. As it moves towards being capable of military annexation, Beijing has also been escalating its non-military activity and its rhetoric towards the island.
