Beijing Sends Maritime Patrol Vessels to Diaoyu Islands During Tensions with Tokyo

Beijing has deployed its coast guard through the waters of the Senkaku islands and military drones near remote Japan's territory as China escalates strains following the Japanese prime minister’s remarks regarding the island of Taiwan.

Patrol Operations

This past Sunday, the Chinese coast guard stated that its vessels conducted a “rights enforcement patrol” through the waters of the Diaoyu islands, which are administered by Japan but also claimed by Beijing.

“Chinese maritime patrol unit 1307 performed surveillance within the territorial waters of the Senkaku islands. This was a lawful patrol operation 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 latest activity 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 military response from Tokyo.

That sparked an angry response from China, which has signalled it expects a retraction from Takaichi.

Taiwan's Position

Beijing asserts the island as its sovereign land and plans to incorporate it under what it terms “unification”. It has left open the use of force. 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 vowing to defend themselves if necessary.

An military assault by Beijing would risk escalating into a regional or global conflict, potentially involving the United States and other allies including Tokyo, which has territory just 110km (68 miles) from Taiwan.

Military Activity

In Taiwan, the military authorities reported this weekend that it had observed 30 Chinese military aircraft, multiple naval vessels and one “official” ship, which was likely the maritime patrol, active near the island over the past 24 hours.

Official charts released showed up to three drones operating near the island and the Japan's territory off its north-east coast, appearing to go unusually near to Yonaguni. PLA movements there are not rare, but uncommon, and Beijing's defense operations in Taiwan’s air defence identification zone generally has been low in the past month.

Late on Saturday, the ministry said Beijing had been carrying out another “combined military exercise” to “harass the airspace and sea around us”. It added Taiwan had dispatched military assets to track the developments. Taiwan documents these operations a few times monthly as part of what the Taiwanese government says is an continuous strategic pressure.

Political Strain

Tokyo has been facing mounting pressure from China since the Japanese official made her remarks, with Beijing's diplomatic representative in the Japanese city prompting a formal protest 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.

Travel and Education Advisory

Late last week, China advised its people to avoid visiting Japan, leading Japan to request China to take “appropriate measures”, though it provided no details.

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

Adding to the tensions, Beijing's administration on Sunday advised students to rethink education plans in Japan, citing what it described as an unstable security environment.

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 record 336,708 foreign nationals 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

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 small-scale encounter; it would likely draw in other powers, including the United States, and could rapidly escalate to a major confrontation with unimaginable consequences.”

Policy Standpoints

The administration in Taipei says the island's residents alone determine their destiny. Japanese leaders have previously avoided publicly mentioning Taiwan when discussing such scenarios, maintaining a “deliberate vagueness” also favoured by Tokyo’s main security ally, the US.

Nevertheless, 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 moves towards being capable of military annexation, Beijing has also been escalating its non-military activity and its rhetoric towards the island.
