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

Beijing has deployed its maritime law enforcement through the waters of the Diaoyu islands and military drones past remote Japan's territory as China ramps up strains following the Japanese prime minister’s comments regarding Taiwan.

Patrol Operations

On Sunday, the Chinese coast guard announced that its vessels conducted a “rights enforcement patrol” through the waters of the Diaoyu islands, which are administered by Tokyo but also claimed by China.

“Chinese maritime patrol unit 1307 performed surveillance within the maritime jurisdiction of the Diaoyu islands. This was a legitimate rights enforcement activity conducted by the Chinese maritime authorities to protect its sovereign claims,” officials declared.

Diplomatic Spat

China and Japan have repeatedly faced off around the islands but the latest activity come amid an escalating political dispute after the Japanese prime minister, Sanae Takaichi, told parliament that if Beijing assaults democratically ruled Taiwan it could trigger a military response from Japan.

That sparked an angry response from Beijing, 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 use of force. Taiwan’s government and people categorically refuse the idea of Beijing's control – preferring to maintain 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 regional or global conflict, potentially involving the United States and other partner nations including Japan, which has land just 68 miles from Taiwan.

Defense Operations

In Taiwan, the defence ministry reported this weekend that it had observed 30 Chinese military aircraft, seven navy ships and one government vessel, which was likely the coast guard, active near the island over the past 24 hours.

Maps provided by the ministry showed up to multiple UAVs flying between the island and the Japanese islands off its northeastern shoreline, seeming to travel particularly close to the nearby Japanese island. PLA movements there are not rare, but uncommon, and Chinese military activity in Taiwan’s air defence identification zone generally has been low in the past month.

Late on Saturday, the defense officials said Beijing had been carrying out another “combined military exercise” 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 the Taiwanese government says is an continuous strategic pressure.

Political Strain

Japan has been experiencing increased strain from Beijing since the Japanese official made her comments, with China’s consul general in Osaka triggering an official complaint from Tokyo by stating that “those who interfere will face consequences”.

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

Warning for Citizens

Late last week, Beijing cautioned its citizens against travelling to Japan, prompting Tokyo to urge Beijing to take “appropriate measures”, though it provided no details.

Multiple carriers from China said on Saturday that tickets to Japan could be cancelled without penalty.

Adding to the tensions, Beijing's administration 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 negative impact on academic institutions in Japan. A historic high of over 336,000 international students were enrolled in Japanese schools last year, according to official data. They included more than 123,000 Chinese students – by far the single biggest group.

Media Response

Late on Saturday, a official press commentary accused Takaichi of staging a political stunt that was “not just dangerously provocative but fundamentally perverse”.

“A clash between Tokyo and Beijing would not be a limited skirmish; it would likely draw in other powers, including the United States, and could rapidly escalate to a large-scale conflict with severe repercussions.”

Policy Standpoints

The administration in Taipei says only its people can decide its future. Officials in Tokyo have traditionally refrained from discussing the island openly when discussing such scenarios, maintaining a “deliberate vagueness” also favoured by Tokyo’s main security ally, the US.

However, Beijing's governing party says the unification of Taiwan with the People’s Republic of China is “inevitable”, and portrays dissent as provocative. As it moves towards being capable of military annexation, China has also been increasing its political operations and its rhetoric towards the island.
