Beijing Dispatches Coast Guard Vessels to Diaoyu Islands Amid Tensions with Tokyo

China has sent its coast guard into the maritime area of the Diaoyu islands and unmanned aerial vehicles past outlying Japan's territory as China ramps up strains following the Japanese prime minister’s remarks regarding Taiwan.

Rights Enforcement Activities

On Sunday, the China's maritime patrol announced that its vessels carried out a “lawful patrol operation” through the waters of the Diaoyu islands, which are administered by Tokyo but also asserted as territory by China.

“China coast guard vessel 1307 formation conducted patrols within the maritime jurisdiction of the Senkaku islands. This was a lawful patrol operation conducted by the Chinese maritime authorities to protect its sovereign claims,” officials declared.

Diplomatic Spat

Beijing and Tokyo have repeatedly faced off around the islands but the recent developments come amid an intensifying diplomatic spat 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 sparked an angry response from China, which has indicated it demands a withdrawal from Takaichi.

Taiwan's Position

China claims Taiwan as its own territory and plans to incorporate it under what it describes as “reunification”. It has not ruled out the use of force. Taiwan’s government and people overwhelmingly reject the idea of Beijing's control – preferring to maintain the status quo without explicitly declaring themselves independent, but pledging to protect their sovereignty if required.

An attack or invasion by Beijing would threaten to spiral into a international confrontation, possibly drawing in the United States and other allies including Tokyo, which has land just 68 miles from the island.

Defense Operations

On the island, the military authorities reported this weekend that it had observed 30 Chinese military aircraft, multiple naval vessels and one “official” ship, which was probably the maritime patrol, active near the territory over the past 24 hours.

Official charts released showed up to multiple UAVs flying between Taiwan and the Japan's territory off its northeastern shoreline, seeming to travel unusually near to the nearby Japanese island. Chinese military transits there are not rare, but uncommon, and Beijing's defense operations in the island's ADIZ generally has been low in the past month.

Late on Saturday, the defense officials said Beijing had been conducting another “joint combat patrol” to “harass the airspace and sea around us”. It added Taiwan had dispatched military assets to monitor the situation. The island reports such Chinese patrols a few times monthly as part of what the Taiwanese government says is an ongoing military pressure campaign.

Diplomatic Pressure

Japan has been experiencing increased strain from Beijing since the Japanese official made her comments, with China’s consul general in the Japanese city triggering an official complaint from Tokyo by stating that “the dirty head that sticks itself out must be cut off”.

China then summoned the Japanese ambassador for the first time in more than two years, and China’s defence ministry declared that any Tokyo's involvement would be doomed to fail.

Warning for Citizens

Late last week, Beijing cautioned its citizens against travelling to Japan, prompting Tokyo to urge Beijing to take “suitable actions”, though it provided no details.

Multiple carriers from China announced this weekend that tickets to Japan could be cancelled without penalty.

Adding to the tensions, Beijing's administration 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 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.

Media Response

Earlier this weekend, a Chinese state media editorial charged the Japanese official with performing a diplomatic maneuver 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 powers, including the US, and could quickly spiral into a major confrontation with unimaginable consequences.”

Strategic Positions

The government of Taiwan says the island's residents alone determine their destiny. Officials in Tokyo have previously avoided publicly mentioning Taiwan when discussing such scenarios, maintaining a “deliberate vagueness” also preferred by Tokyo’s main security ally, the US.

However, China’s ruling Communist party says the incorporation of the island with the People’s Republic of China is “inevitable”, 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 statements towards the island.
