China Dispatches Coast Guard Ships to Senkaku Islands During Dispute with Tokyo

Beijing has sent its coast guard through the maritime area of the Senkaku islands and unmanned aerial vehicles past remote Japan's territory as China escalates strains following the Japan's leader's remarks regarding the island of Taiwan.

Patrol Operations

On Sunday, the Chinese coast guard announced that its vessels carried out a “lawful patrol operation” through the territorial seas of the Senkaku, which are administered by Tokyo but also claimed by China.

“China coast guard vessel 1307 formation conducted patrols within the territorial waters of the Diaoyu islands. This was a legitimate rights enforcement activity conducted by the Chinese maritime authorities to uphold its rights and interests,” the statement said.

Bilateral Tensions

China and Japan have consistently clashed around the islands but the latest activity occur during an intensifying diplomatic spat after the Japanese prime minister, the Japanese official, told parliament that if China attack democratically ruled Taiwan it might provoke a armed reaction from Japan.

That provoked a furious reaction from Beijing, which has signalled it expects a withdrawal from the Japanese official.

Island's Stance

China claims the island 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 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 Beijing would threaten to spiral into a regional or global conflict, potentially involving the US and other allies including Tokyo, which has land just 68 miles from Taiwan.

Defense Operations

In Taiwan, the defence ministry said on Sunday morning that it had observed 30 Chinese military aircraft, multiple naval vessels and one “official” ship, which was probably the maritime patrol, active near the island over the previous day.

Maps provided by the ministry showed up to multiple UAVs flying between Taiwan and the Japanese islands off its northeastern shoreline, appearing to go particularly close to Yonaguni. PLA movements there are not rare, but uncommon, and Chinese military activity in the island's ADIZ generally has been minimal in the past month.

Late on Saturday, the defense officials said China had been conducting another “combined military exercise” to “harass the airspace and sea around us”. It noted the island had sent its own aircraft and ships to track the developments. The island documents these operations a few times monthly 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 remarks, with Beijing's diplomatic representative in Osaka triggering an official complaint from Tokyo by stating that “the dirty head that sticks itself out must be cut off”.

Beijing then called in Japan's diplomat for the first occasion since 2023, and Beijing's military authorities stated that any Japanese intervention would be certain to collapse.

Travel and Education Advisory

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

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

In another escalation, China’s government on the weekend advised students to rethink education plans in Japan, citing what it characterized as an volatile safety situation.

While the advice does not amount to a ban, 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 official data. They included more than 123,000 Chinese students – by far the largest demographic.

Media Response

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 clash between Tokyo and Beijing would not be a small-scale encounter; it would likely draw in other nations, including the US, and could rapidly escalate to a large-scale conflict 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 discussing such scenarios, maintaining a “deliberate vagueness” also preferred by Japan's primary defense partner, 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 rhetoric towards the island.
