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

China has sent its maritime law enforcement through the maritime area of the Senkaku islands and military drones past remote Japanese territory as Beijing escalates strains over the Japan's leader's remarks regarding Taiwan.

Patrol Operations

On Sunday, the Chinese coast guard stated that its ships conducted a “lawful patrol operation” through the waters of the Diaoyu islands, which are under the control of Japan but also asserted as territory by Beijing.

“Chinese maritime patrol unit 1307 conducted patrols within the territorial waters of the Diaoyu islands. This was a lawful patrol operation undertaken by the Chinese maritime authorities to uphold its rights and interests,” the statement said.

Diplomatic Spat

China and Japan have repeatedly faced off around the disputed territory 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 could trigger a armed reaction from Japan.

That sparked an angry response from China, which has signalled it expects a withdrawal from the Japanese official.

Island's Stance

China claims Taiwan as its sovereign land and plans to incorporate it under what it describes as “unification”. It has left open the military option. Taiwan’s government and citizens overwhelmingly reject the idea of Beijing's control – choosing to preserve the current situation without formally announcing independence, but vowing to defend themselves if required.

An military assault by China would threaten to spiral into a international confrontation, potentially involving the US and other partner nations including Tokyo, which has territory just 68 miles from the island.

Military Activity

On the island, the military authorities said on Sunday morning that it had detected 30 Chinese military aircraft, multiple naval vessels and one “official” ship, which was probably the maritime patrol, operating around the island over the previous day.

Official charts released showed up to three drones flying between Taiwan and the Japan's territory off its northeastern shoreline, 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 the past month.

Earlier this weekend, the ministry said Beijing had been conducting another “joint combat patrol” to “harass the airspace and sea around us”. It noted the island had sent its own aircraft and ships 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

Japan has been experiencing increased strain from Beijing since the Japanese official made her comments, with Beijing's diplomatic representative in the Japanese city prompting a formal protest from Japan 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 China’s defence ministry stated that any Japanese intervention would be certain to collapse.

Warning for Citizens

On Friday, Beijing advised its people to avoid visiting Japan, leading Japan to request China to take “appropriate measures”, though it did not elaborate.

Three Chinese airlines said on Saturday that flights to Tokyo could be refunded or changed for free.

In another escalation, Beijing's administration on the weekend advised students to rethink education plans in Japan, citing what it described as an unstable security environment.

Although not an outright prohibition, a dramatic reduction in the number of Chinese students could have a negative impact on Japanese universities. A historic high of over 336,000 international students were enrolled in Japanese schools last year, according to education statistics. They included more than 123,000 Chinese students – by far the single biggest group.

Official Commentary

Late on Saturday, a Chinese state media editorial accused Takaichi of staging a political stunt that was “not just dangerously provocative but fundamentally perverse”.

“A conflict between Japan and China would not be a small-scale encounter; it would probably involve other powers, including the US, and could quickly spiral into a large-scale conflict with severe repercussions.”

Strategic Positions

The administration in Taipei says only its people can decide its future. 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 United States.

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