China Dispatches Coast Guard Ships to Diaoyu Islands During Tensions with Tokyo

China has sent its coast guard through the maritime area of the Senkaku islands and unmanned aerial vehicles near remote Japanese territory as China escalates strains over the Japanese prime minister’s remarks regarding the island of Taiwan.

Patrol Operations

On Sunday, the China's maritime patrol stated that its vessels conducted a “lawful patrol operation” through the waters of the Senkaku, which are administered by Tokyo but also asserted as territory by Beijing.

“China coast guard vessel 1307 formation performed surveillance within the maritime jurisdiction of the Senkaku islands. This was a legitimate rights enforcement activity conducted by the China coast guard to uphold its rights and interests,” the statement said.

Diplomatic Spat

China and Japan have repeatedly faced off around the islands but the recent developments occur during an escalating political dispute after the Japanese prime minister, the Japanese official, told parliament that if China attack democratically ruled Taiwan it might provoke a military response from Tokyo.

That provoked a furious reaction from China, which has indicated it demands a withdrawal from the Japanese official.

Taiwan's Position

China claims the island as its own territory and intends to annex it under what it terms “reunification”. It has left open the use of force. Taiwan’s government and people categorically refuse the prospect of Chinese rule – preferring to maintain the current situation without explicitly declaring themselves independent, but pledging to protect their sovereignty if required.

An attack or invasion by Beijing would risk escalating into a regional or global conflict, possibly drawing in the United States and other allies including Japan, which has land just 68 miles from Taiwan.

Defense Operations

On the island, the military authorities said on Sunday morning that it had observed three dozen PLA planes, multiple naval vessels and one government vessel, which was likely the maritime patrol, active near the island over the past 24 hours.

Maps provided by the ministry showed up to multiple UAVs flying between the island and the Japan's territory off its north-east coast, 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 minimal in the past month.

Late on Saturday, the ministry said Beijing had been carrying out another “joint combat patrol” to “test our defensive capabilities”. It noted the island had dispatched military assets to monitor the situation. Taiwan reports such Chinese patrols a few times monthly as part of what Taipei says is an continuous strategic pressure.

Political Strain

Japan has been facing mounting pressure from Beijing since the Japanese official made her comments, with Beijing's diplomatic representative 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 occasion since 2023, and Beijing's military authorities declared that any Japanese intervention would be doomed to fail.

Warning for Citizens

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.

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 described as an volatile safety situation.

While the advice does not amount to a ban, a significant decrease in the population of learners from China could have a negative impact on academic institutions in Japan. A historic high of over 336,000 international students were studying in Japan last year, according to official data. They featured over 123,000 learners from China – by far the single biggest group.

Official Commentary

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

“A conflict between Japan and China would not be a small-scale encounter; it would likely draw in other nations, including the US, and could quickly spiral into a large-scale conflict with severe repercussions.”

Policy Standpoints

The government of Taiwan says the island's residents alone determine their destiny. Officials in Tokyo have traditionally refrained from publicly mentioning Taiwan when addressing potential conflicts, maintaining a “deliberate vagueness” also favoured by Tokyo’s main security ally, the US.

Nevertheless, China’s ruling Communist party says the incorporation of the island with the People’s Republic of China is “inevitable”, and portrays dissent as provocative. As it advances toward potential armed takeover, Beijing has also been escalating its non-military activity and its statements towards Taiwan.
