China Dispatches Coast Guard Vessels to Diaoyu Islands During Tensions with Tokyo

China has sent its maritime law enforcement into the maritime area of the Diaoyu islands and unmanned aerial vehicles past remote Japan's territory as China ramps up tensions following the Japan's leader's comments regarding the island of Taiwan.

Patrol Operations

On Sunday, the China's maritime patrol stated that its vessels conducted a “lawful patrol operation” through the territorial seas of the Senkaku, which are administered by Tokyo 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,” the statement said.

Bilateral Tensions

China and Japan have consistently clashed around the islands but the latest activity occur during an escalating political dispute after the Japanese prime minister, Sanae Takaichi, told parliament that if Beijing assaults the self-governing island of Taiwan it might provoke a military response from Tokyo.

That provoked a furious reaction from Beijing, which has indicated it demands a retraction from Takaichi.

Taiwan's Position

Beijing asserts Taiwan as its own territory and plans to incorporate it under what it terms “unification”. It has left open the military option. The island's administration and citizens overwhelmingly reject the prospect of Chinese rule – preferring to maintain the current situation without formally announcing independence, but vowing to defend themselves if required.

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

Military Activity

On the island, the military authorities said on Sunday morning that it had observed 30 Chinese military aircraft, seven navy ships and one “official” ship, which was likely the coast guard, active near the territory over the previous day.

Official charts released showed up to multiple UAVs operating near the island and the Japan's territory off its northeastern shoreline, seeming to travel particularly close to the nearby Japanese island. Chinese military transits there are not rare, but infrequent, and Beijing's defense operations in the island's ADIZ generally has been minimal in recent weeks.

Earlier this weekend, the defense officials said Beijing had been conducting another “combined military exercise” to “test our defensive capabilities”. It added Taiwan had dispatched military assets to monitor the situation. The island documents these operations a few times monthly as part of what Taipei says is an continuous strategic pressure.

Political Strain

Tokyo has been experiencing increased strain from Beijing since the Japanese official made her remarks, with China’s consul general in Osaka prompting a formal protest from Japan by commenting that “those who interfere will face consequences”.

China then summoned the Japanese ambassador for the first time in more than two years, and Beijing's military authorities stated that any Japanese intervention would be doomed to fail.

Travel and Education Advisory

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

Multiple carriers from China announced this weekend that flights to Tokyo could be refunded or changed for free.

In another escalation, China’s government on Sunday advised students to rethink education plans in Japan, citing what it characterized as an volatile safety situation.

Although not an outright prohibition, a dramatic reduction in the population of learners from China could have a negative impact on academic institutions in Japan. A record 336,708 foreign nationals were enrolled in Japanese schools last year, according to official data. They featured over 123,000 learners from China – by far the largest demographic.

Official Commentary

Late on Saturday, a Chinese state media editorial charged the Japanese official with performing a diplomatic maneuver that was “both reckless and fundamentally flawed”.

“A clash between Tokyo and Beijing would not be a small-scale encounter; it would likely draw in other powers, 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 traditionally refrained from discussing the island openly when addressing potential conflicts, maintaining a “strategic ambiguity” also favoured by Japan's primary defense partner, the US.

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