Beijing Sends Maritime Patrol Vessels to Diaoyu Islands Amid Dispute with Tokyo

Beijing has deployed its maritime law enforcement through the waters of the Senkaku islands and military drones near remote Japan's territory as Beijing escalates tensions following the Japan's leader's comments regarding Taiwan.

Patrol Operations

This past Sunday, the China's maritime patrol announced that its vessels carried out a “lawful patrol operation” through the waters of the Senkaku, which are under the control of Tokyo but also claimed by China.

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

Diplomatic Spat

Beijing and Tokyo have repeatedly faced off around the disputed territory but the recent developments occur during an intensifying diplomatic spat after the Japan's leader, the Japanese official, addressed lawmakers that if Beijing assaults the self-governing island of Taiwan it might provoke a military response from Japan.

That sparked an angry response from Beijing, which has indicated it demands a retraction from the Japanese official.

Island's Stance

Beijing asserts the island as its sovereign land and plans to incorporate it under what it terms “unification”. It has not ruled out the use of force. The island's administration and people categorically refuse the prospect of Chinese rule – choosing to preserve the status quo without explicitly declaring themselves independent, but vowing to defend themselves if necessary.

An attack or invasion by Beijing would risk escalating into a international confrontation, potentially involving the US and other partner nations including Tokyo, which has territory just 110km (68 miles) from Taiwan.

Defense Operations

On the island, the military authorities said on Sunday morning that it had observed three dozen PLA planes, multiple naval vessels and one government vessel, which was probably the maritime patrol, operating around the territory over the past 24 hours.

Maps provided by the ministry showed up to three drones operating near Taiwan and the Japanese islands off its northeastern shoreline, seeming to travel particularly close to Yonaguni. Chinese military transits there are not rare, but infrequent, and Beijing's defense operations in the island's ADIZ generally has been low in recent weeks.

Late on Saturday, the defense officials said China had been conducting another “joint combat patrol” to “test our defensive capabilities”. It noted the island had dispatched military assets to monitor the situation. Taiwan documents these operations a couple of times a month as part of what the Taiwanese government says is an ongoing military pressure campaign.

Political Strain

Japan has been experiencing increased strain from Beijing since the Japanese official made her comments, with Beijing's diplomatic representative in the Japanese city prompting a formal protest from Tokyo by stating that “the dirty head that sticks itself out must be cut off”.

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

Travel and Education Advisory

Late last week, China advised its people to avoid visiting 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.

In another escalation, Beijing's administration on Sunday advised students to rethink education plans in Japan, citing what it characterized as an volatile safety situation.

While the advice does not amount to a ban, a dramatic reduction in the number of Chinese students could have a negative impact on Japanese universities. A historic high of over 336,000 international students were studying in Japan last year, according to education statistics. They featured over 123,000 learners from China – by far the largest demographic.

Media Response

Earlier this weekend, a official press commentary charged the Japanese official with performing a political stunt that was “both reckless and fundamentally flawed”.

“A clash between Tokyo and Beijing would not be a limited skirmish; it would probably involve other nations, including the United States, and could quickly spiral into a large-scale conflict with severe repercussions.”

Policy Standpoints

The administration in Taipei says only its people can decide its future. Japanese leaders have traditionally refrained from discussing the island openly when discussing such scenarios, maintaining a “deliberate vagueness” also preferred by Tokyo’s main security ally, 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 escalating its non-military activity and its statements towards Taiwan.
