Beijing Sends Coast Guard Ships to Diaoyu Islands Amid Dispute with Tokyo

China has sent its maritime law enforcement into the maritime area of the Senkaku islands and military drones past outlying Japanese territory as Beijing escalates tensions following the Japanese prime minister’s comments regarding the island of Taiwan.

Rights Enforcement Activities

On Sunday, the China's maritime patrol stated that its ships conducted a “lawful patrol operation” through the territorial seas of the Senkaku, which are under the control of Japan but also asserted as territory by Beijing.

“Chinese maritime patrol unit 1307 conducted patrols within the territorial waters of the Senkaku 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 come amid an intensifying diplomatic spat after the Japan's leader, the Japanese official, told parliament that if China attack democratically ruled Taiwan it might provoke a armed reaction from Japan.

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

Taiwan's Position

China claims Taiwan as its sovereign land and intends to annex it under what it terms “unification”. It has not ruled out the use of force. Taiwan’s government and citizens overwhelmingly reject the prospect of Chinese rule – choosing to preserve the current situation without explicitly declaring themselves independent, but pledging to protect their sovereignty if required.

An attack or invasion by China would threaten to spiral into a international confrontation, potentially involving the United States and other partner nations including Japan, which has land just 110km (68 miles) from the island.

Military Activity

In Taiwan, the military authorities reported this weekend that it had observed three dozen PLA planes, multiple naval vessels and one government vessel, which was likely the maritime patrol, operating around the island over the past 24 hours.

Maps provided by the ministry showed up to three drones operating near the island and the Japan's territory off its northeastern shoreline, appearing to go unusually near to the nearby Japanese island. Chinese military transits there are occasional, but infrequent, and Beijing's defense operations in the island's ADIZ generally has been low in recent weeks.

Earlier this weekend, the defense officials said China 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. Taiwan reports such Chinese patrols a couple of times a month as part of what the Taiwanese government says is an ongoing military pressure campaign.

Diplomatic Pressure

Tokyo has been facing mounting pressure from Beijing since the Japanese official made her comments, with China’s consul general in the Japanese city triggering an official complaint from Japan by commenting that “the dirty head that sticks itself out must be cut off”.

China then summoned the Japanese ambassador for the first occasion since 2023, and Beijing's military authorities stated that any Tokyo's involvement would be doomed to fail.

Travel and Education Advisory

Late last week, Beijing cautioned its citizens against travelling to Japan, prompting Tokyo to urge Beijing to take “suitable actions”, though it did not elaborate.

Multiple carriers from China said on Saturday that flights to Tokyo could be cancelled without penalty.

Adding to the tensions, China’s government on Sunday urged its citizens to “carefully reconsider” studying in Japan, citing what it characterized as an unstable security environment.

While the advice does not amount to a ban, a significant decrease 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 enrolled in Japanese schools last year, according to education statistics. They featured over 123,000 learners from China – by far the largest demographic.

Media Response

Late on Saturday, a official press commentary accused Takaichi of staging a diplomatic maneuver that was “both reckless and fundamentally flawed”.

“A clash between Tokyo and Beijing would not be a small-scale encounter; it would likely draw in other nations, including the US, and could quickly spiral into a large-scale conflict with unimaginable consequences.”

Policy Standpoints

The administration in Taipei says the island's residents alone determine their destiny. Officials in Tokyo have traditionally refrained from publicly mentioning Taiwan when discussing such scenarios, maintaining a “deliberate vagueness” also preferred by Japan's primary defense partner, the United States.

However, Beijing's governing party says the incorporation of the island with the People’s Republic of China is “inevitable”, and casts any opposition to it as escalatory. As it advances toward potential armed takeover, China has also been increasing its political operations and its statements towards Taiwan.
