Beijing Dispatches Maritime Patrol Vessels to Diaoyu Islands Amid Tensions with Japan

Beijing has sent its maritime law enforcement into the maritime area of the Senkaku islands and military drones near outlying Japan's territory as Beijing ramps up tensions over the Japanese prime minister’s remarks regarding the island of Taiwan.

Rights Enforcement Activities

This past Sunday, the China's maritime patrol stated that its ships carried out a “lawful patrol operation” 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 conducted by the Chinese maritime authorities to uphold its rights and interests,” officials declared.

Diplomatic Spat

China and Japan have repeatedly faced off around the islands but the latest activity come amid an intensifying diplomatic spat after the Japan's leader, Sanae Takaichi, addressed lawmakers that if China attack the self-governing island of Taiwan it might provoke a military response from Tokyo.

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

Taiwan's Position

Beijing asserts Taiwan as its sovereign land and plans to incorporate it under what it describes as “reunification”. It has left open the military option. Taiwan’s government 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 necessary.

An attack or invasion by China would risk escalating into a international confrontation, possibly drawing in the US and other partner nations including Japan, which has territory just 110km (68 miles) from the island.

Military Activity

On the island, the defence ministry reported this weekend that it had detected three dozen PLA planes, multiple naval vessels and one “official” ship, which was likely the maritime patrol, active near the territory over the previous day.

Maps provided by the ministry showed up to multiple UAVs flying between Taiwan and the Japan's territory off its north-east coast, appearing to go particularly close to Yonaguni. PLA movements there are not rare, but uncommon, and Chinese military activity in the island's ADIZ generally has been low in recent weeks.

Earlier this weekend, the defense officials said China had been carrying out another “combined military exercise” to “harass the airspace and sea around us”. It noted Taiwan had dispatched military assets to monitor the situation. Taiwan documents these operations a few times monthly as part of what the Taiwanese government says is an continuous strategic pressure.

Diplomatic Pressure

Japan has been facing mounting pressure from Beijing since Takaichi made her comments, with China’s consul general in the Japanese city triggering an official complaint 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 stated that any Japanese intervention would be certain to collapse.

Travel and Education Advisory

Late last week, China cautioned its citizens against travelling to 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 cancelled without penalty.

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

Although not an outright prohibition, a significant decrease in the number of Chinese students 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 official data. They featured over 123,000 learners from China – by far the largest demographic.

Official Commentary

Earlier this weekend, a Chinese state media editorial charged the Japanese official with performing a political stunt that was “not just dangerously provocative but fundamentally perverse”.

“A conflict between Japan and China would not be a limited skirmish; it would probably involve other nations, including the US, and could quickly spiral into a large-scale conflict with unimaginable consequences.”

Strategic Positions

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 United States.

However, Beijing's governing party says the incorporation of the island with the People’s Republic of China is “unavoidable”, 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 Taiwan.
