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

Beijing has deployed its coast guard through the waters of the Senkaku islands and unmanned aerial vehicles near remote Japan's territory as China ramps up strains following the Japanese prime minister’s remarks regarding Taiwan.

Rights Enforcement Activities

On Sunday, the China's maritime patrol stated that its ships conducted a “rights enforcement patrol” through the waters of the Senkaku, which are administered by Tokyo but also asserted as territory by Beijing.

“China coast guard vessel 1307 formation conducted patrols within the maritime jurisdiction 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.

Bilateral Tensions

Beijing and Tokyo have consistently clashed around the disputed territory but the recent developments come amid an escalating political dispute after the Japan's leader, the Japanese official, addressed lawmakers that if Beijing assaults the self-governing island of Taiwan it could trigger a military response from Japan.

That provoked a furious reaction from China, which has indicated it demands a withdrawal from the Japanese official.

Taiwan's Position

China claims the island as its sovereign land and plans to incorporate it under what it describes as “reunification”. It has not ruled out the military option. The island's administration and people overwhelmingly reject the prospect of Chinese rule – choosing to preserve the status quo without explicitly declaring themselves independent, but pledging to protect their sovereignty if required.

An military assault by Beijing would threaten to spiral into a international confrontation, potentially involving the US and other partner nations including Tokyo, which has land just 110km (68 miles) from Taiwan.

Military Activity

On the island, the defence ministry reported this weekend that it had observed three dozen PLA planes, seven navy ships and one government vessel, which was probably the coast guard, operating around the island over the previous day.

Maps provided by the ministry showed up to multiple UAVs flying between Taiwan and the Japanese islands off its northeastern shoreline, appearing to go unusually near to Yonaguni. PLA movements there are occasional, but infrequent, and Beijing's defense operations in the island's ADIZ generally has been minimal in recent weeks.

Earlier this weekend, the ministry said Beijing had been carrying out another “joint combat patrol” to “harass the airspace and sea around us”. It noted Taiwan had sent its own aircraft and ships to monitor the situation. Taiwan 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 China since Takaichi made her comments, with China’s consul general in the Japanese city triggering an official complaint from Tokyo by commenting that “those who interfere will face consequences”.

China then called in Japan's diplomat for the first occasion since 2023, and Beijing's military authorities declared that any Japanese intervention would be certain to collapse.

Travel and Education Advisory

Late last week, Beijing advised its people to avoid visiting Japan, prompting Tokyo to urge Beijing to take “suitable actions”, though it did not elaborate.

Three Chinese airlines announced this weekend that tickets to Japan could be refunded or changed for free.

In another escalation, China’s government on the weekend 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 population of learners from China could have a detrimental effect on academic institutions in Japan. 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 single biggest group.

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 powers, including the US, and could rapidly escalate to a large-scale conflict with unimaginable consequences.”

Policy Standpoints

The government of Taiwan says the island's residents alone determine their destiny. Japanese leaders have traditionally refrained from discussing the island openly when discussing such scenarios, maintaining a “strategic ambiguity” also favoured by Tokyo’s main security ally, the United States.

Nevertheless, Beijing's governing party says the unification of Taiwan with the mainland China is “inevitable”, and portrays dissent as provocative. As it advances toward potential armed takeover, China has also been escalating its non-military activity and its statements towards Taiwan.
