China Dispatches Maritime Patrol Ships to Diaoyu Islands During Tensions with Tokyo

China has sent its coast guard through the waters of the Diaoyu islands and unmanned aerial vehicles near remote Japan's territory as Beijing ramps up tensions following the Japanese prime minister’s comments regarding the island of Taiwan.

Rights Enforcement Activities

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

“Chinese maritime patrol unit 1307 performed surveillance within the maritime jurisdiction of the Diaoyu islands. This was a legitimate rights enforcement activity undertaken by the China coast guard to protect its sovereign claims,” the statement said.

Bilateral Tensions

Beijing and Tokyo have repeatedly faced off around the islands but the recent developments occur during an escalating political dispute after the Japan's leader, the Japanese official, addressed lawmakers that if China attack democratically ruled Taiwan it could trigger a military response from Japan.

That sparked an angry response from China, which has signalled it expects a withdrawal from the Japanese official.

Island's Stance

China claims the island as its own territory and plans to incorporate it under what it terms “unification”. It has not ruled out the use of force. The island's administration and citizens overwhelmingly reject the prospect of Chinese rule – choosing to preserve the status quo without formally announcing independence, but vowing to defend themselves if necessary.

An attack or invasion by Beijing would threaten to spiral into a international confrontation, potentially involving the US and other allies including Japan, which has territory just 68 miles from Taiwan.

Military Activity

On the island, the military authorities reported this weekend that it had detected 30 Chinese military aircraft, seven navy ships and one “official” ship, which was likely the maritime patrol, active near the territory over the previous day.

Official charts released showed up to multiple UAVs operating near the island and the Japanese islands off its northeastern shoreline, appearing to go unusually near to the nearby Japanese island. PLA movements there are not rare, but uncommon, and Beijing's defense operations in Taiwan’s air defence identification zone generally has been minimal in the past month.

Earlier this weekend, the defense officials said Beijing had been conducting another “joint combat patrol” 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 ongoing military pressure campaign.

Diplomatic Pressure

Japan has been facing mounting pressure from China since the Japanese official made her remarks, with China’s consul general in Osaka prompting a formal protest 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 Beijing's military authorities declared that any Japanese intervention would be certain to collapse.

Travel and Education Advisory

On Friday, Beijing 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, Beijing's administration on the weekend advised students to rethink education plans in Japan, citing what it characterized as an unstable security environment.

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 studying in Japan last year, according to education statistics. They included more than 123,000 Chinese students – by far the single biggest group.

Official Commentary

Earlier this weekend, a Chinese state media editorial accused Takaichi of staging a political stunt that was “not just dangerously provocative but fundamentally perverse”.

“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 quickly spiral into a major confrontation with severe repercussions.”

Strategic Positions

The government of Taiwan says only its people can decide its future. Japanese leaders have previously avoided discussing the island openly when addressing potential conflicts, maintaining a “deliberate vagueness” also favoured by Japan's primary defense partner, the United States.

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