China Dispatches Coast Guard Ships to Senkaku Islands Amid Tensions with Japan

China has sent its maritime law enforcement through the waters of the Senkaku islands and military drones near remote Japanese territory as Beijing escalates strains over the Japanese prime minister’s remarks regarding Taiwan.

Rights Enforcement Activities

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

“Chinese maritime patrol unit 1307 conducted patrols within the maritime jurisdiction of the Senkaku islands. This was a lawful patrol operation conducted by the China coast guard to uphold its rights and interests,” the statement said.

Diplomatic Spat

China and Japan have consistently clashed around the disputed territory but the recent developments come amid an escalating political dispute after the Japan's leader, the Japanese official, told parliament that if China attack the self-governing island of Taiwan it could trigger a armed reaction from Japan.

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

Island's Stance

China claims the island as its sovereign land and plans to incorporate it under what it describes as “unification”. It has left open the use of force. The island's administration and people overwhelmingly reject the idea of Beijing's control – choosing to preserve the status quo without formally announcing independence, but vowing to defend themselves if necessary.

An military assault by China would threaten to spiral into a international confrontation, possibly drawing in the US and other allies including Tokyo, which has territory just 110km (68 miles) from the island.

Military Activity

On the island, the military authorities said on Sunday morning that it had detected 30 Chinese military aircraft, multiple naval vessels and one “official” ship, which was likely the coast guard, active near the territory over the previous day.

Official charts released showed up to multiple UAVs flying between Taiwan and the Japanese islands off its northeastern shoreline, appearing to go unusually near to Yonaguni. PLA movements there are not rare, 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 “combined military exercise” to “test our defensive capabilities”. It added Taiwan had dispatched military assets to track the developments. The island documents these operations a couple of times a month as part of what Taipei says is an ongoing military pressure campaign.

Diplomatic Pressure

Tokyo has been experiencing increased strain from China since Takaichi made her remarks, with China’s consul general in Osaka prompting a formal protest from Japan by stating that “those who interfere will face consequences”.

China then called in Japan's diplomat for the first occasion since 2023, and China’s defence ministry stated that any Tokyo's involvement would be certain to collapse.

Travel and Education Advisory

Late last week, China cautioned its citizens against travelling to Japan, leading Japan to request China to take “appropriate measures”, though it provided no details.

Three Chinese airlines announced this weekend that tickets to Japan could be refunded or changed for free.

In another escalation, China’s government on Sunday urged its citizens to “carefully reconsider” studying in Japan, citing what it described as an volatile safety situation.

Although not an outright prohibition, a dramatic reduction 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 education statistics. They featured over 123,000 learners from China – by far the largest demographic.

Official Commentary

Late on Saturday, a Chinese state media editorial charged the Japanese official with performing a political stunt that was “both reckless and fundamentally flawed”.

“A conflict between Japan and China would not be a small-scale encounter; it would probably involve other nations, including the US, and could rapidly escalate to a large-scale conflict with unimaginable consequences.”

Policy Standpoints

The administration in Taipei says only its people can decide its future. Officials in Tokyo have previously avoided publicly mentioning Taiwan 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 “inevitable”, and portrays dissent as provocative. As it advances toward potential armed takeover, China has also been increasing its political operations and its rhetoric towards the island.
