Beijing Dispatches Coast Guard Ships to Senkaku Islands Amid Dispute with Japan

Beijing has sent its maritime law enforcement into the maritime area of the Diaoyu islands and unmanned aerial vehicles past outlying Japan's territory as China ramps up strains over the Japanese prime minister’s comments regarding Taiwan.

Patrol Operations

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

“Chinese maritime patrol unit 1307 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,” the statement said.

Bilateral Tensions

China and Japan have consistently clashed around the disputed territory but the recent developments come amid an intensifying diplomatic spat after the Japanese prime minister, the Japanese official, addressed lawmakers that if Beijing assaults the self-governing island of Taiwan it could trigger a armed reaction from Japan.

That sparked an angry response from China, which has indicated it demands a retraction from Takaichi.

Island's Stance

China claims the island as its own territory and intends to annex it under what it describes as “unification”. It has left open the use of force. Taiwan’s government and people categorically refuse the idea of Beijing's control – preferring to maintain the current situation without explicitly declaring themselves independent, but pledging to protect their sovereignty if required.

An attack or invasion by Beijing would risk escalating into a regional or global conflict, possibly drawing in the US and other allies including Tokyo, which has territory just 110km (68 miles) from the island.

Defense Operations

In Taiwan, the military authorities reported this weekend that it had observed 30 Chinese military aircraft, seven navy ships and one “official” ship, which was probably the coast guard, operating around the territory over the previous day.

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

Earlier this weekend, the defense officials said Beijing had been conducting another “combined military exercise” to “harass the airspace and sea around us”. It added Taiwan had dispatched military assets to monitor the situation. 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.

Political Strain

Tokyo has been facing mounting pressure from Beijing since Takaichi made her remarks, with Beijing's diplomatic representative in Osaka triggering an official complaint from Tokyo by commenting that “the dirty head that sticks itself out must be cut off”.

China then called in Japan's diplomat for the first occasion since 2023, and China’s defence ministry declared that any Tokyo's involvement would be doomed to fail.

Travel and Education Advisory

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

Multiple carriers from China said on Saturday that flights to Tokyo could be refunded or changed for free.

Adding to the tensions, Beijing's administration on Sunday urged its citizens to “carefully reconsider” studying in Japan, citing what it characterized as an volatile safety situation.

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 studying in Japan last year, according to education statistics. They included more than 123,000 Chinese students – by far the largest demographic.

Media Response

Earlier this weekend, a official press commentary accused Takaichi of staging a political stunt that was “both reckless and fundamentally flawed”.

“A conflict between Japan and China would not be a small-scale encounter; it would likely draw in other nations, including the United States, and could quickly spiral into a major confrontation with severe repercussions.”

Strategic Positions

The administration in Taipei says only its people can decide its future. Officials in Tokyo have previously avoided discussing the island openly when addressing potential conflicts, maintaining a “strategic ambiguity” also favoured by Tokyo’s main security ally, the United States.

However, China’s ruling Communist party says the incorporation of the island with the mainland China is “unavoidable”, 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 rhetoric towards Taiwan.
