China Sends Maritime Patrol Ships to Senkaku Islands During Tensions with Japan

China has sent its maritime law enforcement into the waters of the Diaoyu islands and unmanned aerial vehicles near outlying Japan's territory as Beijing escalates strains over the Japanese prime minister’s remarks regarding the island of Taiwan.

Patrol Operations

On 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 Japan but also asserted as territory by China.

“China coast guard vessel 1307 formation performed surveillance within the territorial waters 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.

Bilateral Tensions

Beijing and Tokyo have repeatedly faced off around the disputed territory but the recent developments come amid an escalating political dispute after the Japan's leader, Sanae Takaichi, told parliament that if Beijing assaults democratically ruled Taiwan it might provoke a armed reaction from Japan.

That provoked a furious reaction from Beijing, which has indicated it demands a withdrawal from the Japanese official.

Taiwan's Position

Beijing asserts Taiwan as its own territory and intends to annex it under what it describes as “unification”. It has left open the military option. Taiwan’s government and people categorically refuse the prospect of Chinese rule – preferring to maintain the current situation without formally announcing independence, but pledging to protect their sovereignty if required.

An attack or invasion by China would risk escalating into a international confrontation, potentially involving the United States and other partner nations including Tokyo, which has land just 68 miles from the island.

Defense Operations

On the island, the defence ministry said on Sunday morning that it had observed three dozen PLA planes, multiple naval vessels and one government vessel, which was likely the coast guard, active near the territory over the previous day.

Maps provided by the ministry showed up to three drones flying between Taiwan and the Japan's territory off its north-east coast, appearing to go particularly close to Yonaguni. Chinese military transits there are not rare, but uncommon, and Chinese military activity in Taiwan’s air defence identification zone generally has been low in recent weeks.

Late on Saturday, the defense officials said China had been carrying out another “joint combat patrol” to “harass the airspace and sea around us”. It noted Taiwan had sent its own aircraft and ships to track the developments. The island documents these operations a few times monthly as part of what the Taiwanese government says is an continuous strategic pressure.

Diplomatic Pressure

Tokyo has been facing mounting pressure from China since Takaichi made her comments, with Beijing's diplomatic representative in Osaka triggering an official complaint from Tokyo by stating that “the dirty head that sticks itself out must be cut off”.

China then called in Japan's diplomat for the first time in more than two years, and Beijing's military authorities stated that any Tokyo's involvement would be certain to collapse.

Warning for Citizens

Late last week, Beijing cautioned its citizens against travelling to Japan, leading Japan to request China to take “suitable actions”, though it did not elaborate.

Multiple carriers from China said on Saturday that tickets to Japan could be cancelled without penalty.

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 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 education statistics. They included more than 123,000 Chinese students – by far the largest demographic.

Media Response

Earlier this weekend, a official press commentary accused Takaichi of staging a diplomatic maneuver that was “not just dangerously provocative but fundamentally perverse”.

“A conflict between Japan and China would not be a small-scale encounter; it would likely draw in other nations, including the United States, and could rapidly escalate to a major confrontation with unimaginable consequences.”

Strategic Positions

The administration in Taipei says only its people can decide its future. Japanese leaders have previously avoided discussing the island openly when discussing such scenarios, maintaining a “strategic ambiguity” also preferred by Japan's primary defense partner, the US.

However, China’s ruling Communist party says the incorporation of the island with the mainland China is “inevitable”, and casts any opposition to it as escalatory. As it moves towards being capable of military annexation, Beijing has also been increasing its political operations and its statements towards the island.
