China Sends Maritime Patrol Vessels to Diaoyu Islands Amid Dispute with Japan

China has sent its maritime law enforcement into the waters of the Senkaku islands and unmanned aerial vehicles near outlying Japan's territory as Beijing ramps up tensions following the Japan's leader's remarks regarding Taiwan.

Rights Enforcement Activities

On Sunday, the Chinese coast guard 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 China.

“Chinese maritime patrol unit 1307 conducted patrols within the territorial waters of the Senkaku islands. This was a legitimate rights enforcement activity conducted by the China coast guard to protect its sovereign claims,” officials declared.

Bilateral Tensions

China and Japan have repeatedly faced off around the disputed territory but the latest activity occur during an escalating political dispute after the Japan's leader, Sanae Takaichi, told parliament that if China attack democratically ruled Taiwan it might provoke a military response from Japan.

That sparked an angry response from Beijing, which has indicated it demands a retraction from the Japanese official.

Taiwan's Position

Beijing asserts the island as its sovereign land and plans to incorporate it under what it describes as “reunification”. It has left open the use of force. The island's administration and citizens 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 China would risk escalating into a regional or global conflict, possibly drawing in the United States and other partner nations including Tokyo, which has land just 110km (68 miles) from Taiwan.

Military Activity

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, operating around the island over the past 24 hours.

Maps provided by the ministry showed up to three drones flying between the island and the Japanese islands off its northeastern shoreline, seeming to travel unusually near to Yonaguni. Chinese military transits there are occasional, but infrequent, and Chinese military activity in Taiwan’s air defence identification zone generally has been low in recent weeks.

Earlier this weekend, the defense officials said China had been conducting another “joint combat patrol” to “harass the airspace and sea around us”. It noted the island 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 continuous strategic pressure.

Diplomatic Pressure

Tokyo has been facing mounting pressure from Beijing since the Japanese official made her comments, with China’s consul general in the Japanese city 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 declared that any Tokyo's involvement would be doomed to fail.

Warning for Citizens

On Friday, China cautioned its citizens against travelling to Japan, prompting Tokyo to urge Beijing to take “appropriate measures”, though it did not elaborate.

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

In another escalation, Beijing's administration on the weekend urged its citizens to “carefully reconsider” studying in Japan, citing what it described as an unstable security environment.

Although not an outright prohibition, a dramatic reduction in the number of Chinese students could have a detrimental effect on Japanese universities. A record 336,708 foreign nationals were enrolled in Japanese schools last year, according to education statistics. They featured over 123,000 learners from China – by far the single biggest group.

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 clash between Tokyo and Beijing would not be a small-scale encounter; it would probably involve other nations, including the US, and could quickly spiral into a large-scale conflict with severe repercussions.”

Strategic Positions

The administration in Taipei says the island's residents alone determine their destiny. Officials in Tokyo have previously avoided discussing the island openly 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 mainland China is “unavoidable”, 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.
