Beijing Dispatches Coast Guard Vessels to Diaoyu Islands Amid Dispute with Japan

Beijing has sent its coast guard into the maritime area of the Diaoyu islands and unmanned aerial vehicles near remote Japan's territory as Beijing ramps up tensions over the Japanese prime minister’s remarks regarding Taiwan.

Rights Enforcement Activities

On Sunday, the China's maritime patrol stated that its vessels carried out a “lawful patrol operation” through the waters of the Diaoyu islands, which are administered by Tokyo but also asserted as territory by Beijing.

“China coast guard vessel 1307 formation conducted patrols within the territorial waters of the Diaoyu islands. This was a legitimate rights enforcement activity undertaken by the Chinese maritime authorities to uphold its rights and interests,” officials declared.

Bilateral Tensions

Beijing and Tokyo have consistently clashed around the islands but the latest activity come amid an escalating political dispute after the Japan's leader, the Japanese official, addressed lawmakers that if China attack democratically ruled Taiwan it might provoke a military response from Japan.

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

Taiwan's Position

China claims Taiwan as its own territory and plans to incorporate it under what it describes as “reunification”. It has not ruled out the use of force. The island's administration and people overwhelmingly reject the idea of Beijing's control – choosing to preserve the status quo without formally announcing independence, but vowing to defend themselves if required.

An attack or invasion by Beijing would risk escalating into a international confrontation, potentially involving the United States and other allies including Japan, which has land just 68 miles from Taiwan.

Military Activity

In Taiwan, the defence ministry reported this weekend that it had detected three dozen PLA planes, seven navy ships and one government vessel, which was probably the coast guard, active near the territory over the previous day.

Official charts released showed up to multiple UAVs operating near Taiwan and the Japanese islands off its north-east coast, seeming to travel unusually near to Yonaguni. Chinese military transits there are occasional, but uncommon, and Chinese military activity in the island's ADIZ generally has been low in recent weeks.

Late on Saturday, the defense officials said China had been carrying out another “joint combat patrol” to “test our defensive capabilities”. It noted Taiwan had dispatched military assets to monitor the situation. Taiwan reports such Chinese patrols a few times monthly as part of what the Taiwanese government says is an ongoing military pressure campaign.

Diplomatic Pressure

Japan has been facing mounting pressure 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 commenting that “the dirty head that sticks itself out must be cut off”.

Beijing then called in Japan's diplomat 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, Beijing cautioned its citizens against travelling to Japan, prompting Tokyo to urge Beijing to take “appropriate measures”, though it provided no details.

Three Chinese airlines said on Saturday that flights to Tokyo could be cancelled without penalty.

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

Although not an outright prohibition, 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 featured over 123,000 learners from China – by far the single biggest group.

Media Response

Late on Saturday, a official press commentary accused Takaichi of staging a diplomatic maneuver 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.”

Strategic Positions

The government of Taiwan says the island's residents alone determine their destiny. Japanese leaders have traditionally refrained from publicly mentioning Taiwan when discussing such scenarios, maintaining a “deliberate vagueness” also favoured by Japan's primary defense partner, the US.

However, Beijing's governing party says the unification of Taiwan with the mainland China is “unavoidable”, and portrays dissent as provocative. As it advances toward potential armed takeover, China has also been increasing its political operations and its rhetoric towards the island.
