China Sends Maritime Patrol Vessels to Senkaku Islands Amid Tensions with Tokyo

China has sent its coast guard through the waters of the Diaoyu islands and unmanned aerial vehicles past outlying Japan's territory as China escalates tensions following the Japan's leader's comments regarding Taiwan.

Rights Enforcement Activities

This past Sunday, the Chinese coast guard stated that its vessels carried out a “rights enforcement patrol” through the waters of the Senkaku, which are administered by Tokyo but also asserted as territory by Beijing.

“Chinese maritime patrol unit 1307 performed surveillance within the maritime jurisdiction of the Senkaku islands. This was a lawful patrol operation conducted by the Chinese maritime authorities to uphold its rights and interests,” 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, the Japanese official, addressed lawmakers that if Beijing assaults the self-governing island of Taiwan it might provoke a military response from Tokyo.

That provoked a furious reaction from China, which has signalled it expects a retraction from Takaichi.

Island's Stance

Beijing asserts Taiwan as its own territory and intends to annex it under what it describes as “reunification”. It has not ruled out the military option. The island's administration and citizens overwhelmingly reject the prospect of Chinese rule – choosing to preserve the status quo without formally announcing independence, but pledging to protect their sovereignty if necessary.

An attack or invasion by Beijing would risk escalating into a regional or global conflict, potentially involving the United States and other allies including Tokyo, which has land just 110km (68 miles) from Taiwan.

Military Activity

In Taiwan, the military authorities said on Sunday morning that it had observed 30 Chinese military aircraft, multiple naval vessels and one government vessel, which was likely the coast guard, active near the island over the previous day.

Maps provided by the ministry showed up to multiple UAVs operating near the island and the Japanese islands off its north-east coast, seeming to travel particularly close to Yonaguni. PLA movements there are occasional, but infrequent, and Beijing's defense operations in the island's ADIZ generally has been low in recent weeks.

Earlier this weekend, the defense officials said Beijing had been carrying out another “joint combat patrol” to “harass the airspace and sea around us”. It noted the island had sent its own aircraft and ships to track the developments. Taiwan reports such Chinese patrols a couple of times a month as part of what the Taiwanese government says is an ongoing military pressure campaign.

Political Strain

Tokyo has been facing mounting pressure from China since the Japanese official made her comments, with China’s consul general in the Japanese city triggering an official complaint from Japan 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 China’s defence ministry declared that any Tokyo's involvement would be certain to collapse.

Travel and Education Advisory

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.

Three Chinese airlines said on Saturday that flights to Tokyo could be refunded or changed for free.

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

While the advice does not amount to a ban, a dramatic reduction in the population of learners from China could have a detrimental effect on Japanese universities. A record 336,708 foreign nationals were enrolled in Japanese schools last year, according to official data. They included more than 123,000 Chinese students – by far the single biggest group.

Media Response

Late on Saturday, 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 limited skirmish; it would likely draw in other nations, including the US, and could rapidly escalate to a large-scale conflict with unimaginable consequences.”

Strategic Positions

The administration in Taipei says only its people can decide its future. Officials in Tokyo have previously avoided publicly mentioning Taiwan when discussing such scenarios, maintaining a “deliberate vagueness” also preferred by Japan's primary defense partner, the United States.

However, Beijing's governing party says the incorporation of the island with the mainland China is “inevitable”, and casts any opposition to it as escalatory. As it advances toward potential armed takeover, Beijing has also been escalating its non-military activity and its rhetoric towards Taiwan.
