Beijing Dispatches Coast Guard Vessels to Diaoyu Islands Amid Tensions with Tokyo

China has deployed its maritime law enforcement through the waters of the Diaoyu islands and unmanned aerial vehicles near outlying Japanese territory as Beijing ramps up tensions following the Japanese prime minister’s comments regarding Taiwan.

Patrol Operations

On Sunday, the Chinese coast guard announced that its ships carried out a “lawful patrol operation” through the waters of the Senkaku, which are under the control of Tokyo but also asserted as territory by Beijing.

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

Diplomatic Spat

China and Japan have consistently clashed around the disputed territory but the recent developments come amid an escalating political dispute after the Japan's leader, Sanae Takaichi, addressed lawmakers that if China attack democratically ruled Taiwan it might provoke a military response from Tokyo.

That provoked a furious reaction from China, which has signalled it expects a withdrawal from Takaichi.

Island's Stance

Beijing asserts Taiwan as its sovereign land and plans to incorporate it under what it terms “reunification”. It has not ruled out 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, potentially involving the United States and other partner nations including Japan, which has land just 68 miles from the island.

Defense Operations

On the island, the military authorities said on Sunday morning that it had observed 30 Chinese military aircraft, multiple naval vessels and one “official” ship, which was probably the coast guard, active near the island over the past 24 hours.

Official charts released showed up to multiple UAVs flying between Taiwan and the Japan's territory off its north-east coast, seeming to travel unusually near to the nearby Japanese island. PLA movements there are occasional, but infrequent, and Chinese military activity in the island's ADIZ generally has been low in recent weeks.

Earlier this weekend, the defense officials said Beijing had been carrying out another “joint combat patrol” to “test our defensive capabilities”. It noted the island 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 continuous strategic pressure.

Political Strain

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

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

Warning for Citizens

Late last week, China advised its people to avoid visiting Japan, leading Japan to request China to take “suitable actions”, though it did not elaborate.

Three Chinese airlines said on Saturday that flights to Tokyo could be refunded or changed for free.

Adding to the tensions, 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 dramatic reduction in the number of Chinese students could have a detrimental effect on Japanese universities. A record 336,708 foreign nationals were studying in Japan last year, according to official data. They included more than 123,000 Chinese students – by far the single biggest group.

Official Commentary

Earlier this weekend, a Chinese state media editorial accused Takaichi of staging 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 powers, including the US, and could rapidly escalate to a large-scale conflict with unimaginable consequences.”

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 favoured by Tokyo’s main security ally, the US.

Nevertheless, China’s ruling Communist party says the incorporation of the island with the mainland China is “inevitable”, and casts any opposition to it as escalatory. As it advances toward potential armed takeover, Beijing has also been escalating its non-military activity and its rhetoric towards the island.
