China Dispatches Maritime Patrol Vessels to Diaoyu Islands Amid Tensions with Tokyo

China has deployed its maritime law enforcement into the waters of the Senkaku islands and unmanned aerial vehicles past outlying Japan's territory as China ramps up strains following the Japanese prime minister’s remarks regarding the island of Taiwan.

Rights Enforcement Activities

This past Sunday, the China's maritime patrol announced that its ships conducted a “rights enforcement patrol” through the territorial seas of the Senkaku, which are under the control of Tokyo but also claimed by Beijing.

“China coast guard vessel 1307 formation performed surveillance within the territorial waters of the Senkaku islands. This was a lawful patrol operation undertaken by the China coast guard to uphold its rights and interests,” the statement said.

Diplomatic Spat

Beijing and Tokyo have consistently clashed around the islands but the latest activity come amid an escalating political dispute after the Japanese prime minister, the Japanese official, told parliament that if Beijing assaults the self-governing island of Taiwan it could trigger a military response from Japan.

That sparked an angry response from China, which has signalled it expects a retraction from Takaichi.

Taiwan's Position

Beijing asserts the island as its own territory and intends to annex it under what it terms “unification”. It has not ruled out the use of force. Taiwan’s government and citizens categorically refuse the prospect of Chinese rule – preferring to maintain the status quo without explicitly declaring themselves independent, but vowing to defend themselves if required.

An attack or invasion by China would threaten to spiral into a regional or global conflict, potentially involving the US and other allies including Tokyo, which has territory just 110km (68 miles) from Taiwan.

Defense Operations

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 maritime patrol, operating around the island over the past 24 hours.

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 unusually near to the nearby Japanese island. PLA movements there are not rare, but uncommon, and Beijing's defense operations in the island's ADIZ generally has been minimal in the past month.

Earlier this weekend, the ministry said China had been carrying out another “combined military exercise” to “test our defensive capabilities”. It noted Taiwan had sent its own aircraft and ships to track the developments. The island 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 Beijing since the Japanese official made her remarks, with Beijing's diplomatic representative in Osaka triggering an official complaint from Tokyo by stating that “those who interfere will face consequences”.

Beijing 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

Late last week, China advised its people to avoid visiting Japan, leading Japan to request China to take “appropriate measures”, though it did not elaborate.

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

Adding to the tensions, China’s government on Sunday urged its citizens to “carefully reconsider” studying in Japan, citing what it characterized as an volatile safety situation.

Although not an outright prohibition, a dramatic reduction in the number of Chinese students could have a detrimental effect on academic institutions in Japan. A historic high of over 336,000 international students 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 official press commentary 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 likely draw in other nations, including the US, and could quickly spiral into a major confrontation with unimaginable consequences.”

Policy Standpoints

The government of Taiwan says only its people can decide its future. Officials in Tokyo have previously avoided discussing the island openly when addressing potential conflicts, maintaining a “deliberate vagueness” also preferred by Japan's primary defense partner, the US.

Nevertheless, China’s ruling Communist party says the unification of Taiwan with the mainland China is “unavoidable”, and portrays dissent as provocative. As it advances toward potential armed takeover, China has also been increasing its political operations and its statements towards the island.
