China Sends Coast Guard Vessels to Senkaku Islands During Tensions with Japan

Beijing has deployed its maritime law enforcement into the maritime area of the Senkaku islands and unmanned aerial vehicles near remote Japanese territory as Beijing ramps up tensions following the Japanese prime minister’s remarks regarding Taiwan.

Patrol Operations

This past Sunday, the China's maritime patrol announced that its ships carried out a “lawful patrol operation” through the waters of the Senkaku, which are under the control of Tokyo but also asserted as territory by China.

“China coast guard vessel 1307 formation conducted patrols within the maritime jurisdiction of the Diaoyu islands. This was a legitimate rights enforcement activity undertaken by the Chinese maritime authorities to protect its sovereign claims,” officials declared.

Diplomatic Spat

Beijing and Tokyo have consistently clashed around the islands but the recent developments occur during an intensifying diplomatic spat 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 provoked a furious reaction from China, which has indicated it demands a withdrawal from the Japanese official.

Taiwan's Position

China claims the island as its own territory and plans to incorporate it under what it terms “reunification”. It has not ruled out the military option. Taiwan’s government and citizens categorically refuse the idea of Beijing's control – preferring to maintain the current situation without formally announcing independence, but pledging to protect their sovereignty if necessary.

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

Defense Operations

On the island, the military authorities reported this weekend that it had detected 30 Chinese military aircraft, seven navy ships and one “official” ship, which was probably the coast guard, active near the territory over the previous day.

Official charts released showed up to three drones operating near the island and the Japan's territory off its north-east coast, seeming to travel unusually near to Yonaguni. Chinese military transits there are not rare, but uncommon, and Beijing's defense operations in Taiwan’s air defence identification zone generally has been low in recent weeks.

Earlier this weekend, the defense officials said Beijing had been conducting another “combined military exercise” to “harass the airspace and sea around us”. It added the island had sent its own aircraft and ships to monitor the situation. Taiwan documents these operations a couple of times a month as part of what Taipei says is an continuous strategic pressure.

Diplomatic Pressure

Japan has been facing mounting pressure from China since the Japanese official made her remarks, with China’s consul general in Osaka 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 Tokyo's involvement would be certain to collapse.

Travel and Education Advisory

Late last week, China cautioned its citizens against travelling to Japan, prompting Tokyo to urge Beijing to take “suitable actions”, 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 the weekend urged its citizens to “carefully reconsider” studying in Japan, citing what it characterized as an volatile safety situation.

Although not an outright prohibition, a dramatic reduction 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 included more than 123,000 Chinese students – by far the largest demographic.

Official Commentary

Late on Saturday, a official press commentary charged the Japanese official with performing a diplomatic maneuver that was “both reckless and fundamentally flawed”.

“A conflict between Japan and China would not be a small-scale encounter; it would likely draw in other powers, including the US, 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 discussing the island openly when addressing potential conflicts, maintaining a “deliberate vagueness” also preferred by Japan's primary defense partner, the US.

Nevertheless, Beijing's governing party says the unification of Taiwan with the mainland China is “unavoidable”, and casts any opposition to it as escalatory. As it advances toward potential armed takeover, Beijing has also been increasing its political operations and its rhetoric towards the island.
