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

China has deployed its coast guard through the maritime area of the Diaoyu islands and unmanned aerial vehicles near remote Japanese territory as China ramps up tensions following the Japan's leader's comments regarding the island of Taiwan.

Patrol Operations

On Sunday, the Chinese coast guard stated that its ships carried out a “lawful patrol operation” through the waters of the Senkaku, which are administered by Japan but also claimed by Beijing.

“China coast guard vessel 1307 formation performed surveillance within the maritime jurisdiction of the Diaoyu islands. This was a legitimate rights enforcement activity 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 occur during an intensifying diplomatic spat after the Japanese prime minister, the Japanese official, addressed lawmakers that if Beijing assaults the self-governing island of Taiwan it could trigger a armed reaction from Tokyo.

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

Taiwan's Position

Beijing asserts the island as its sovereign land and plans to incorporate it under what it describes as “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 status quo without explicitly declaring themselves independent, but vowing to defend themselves if necessary.

An attack or invasion by Beijing would threaten to spiral into a regional or global conflict, potentially involving the United States and other partner nations including Japan, which has territory just 68 miles from the island.

Defense Operations

In Taiwan, the military authorities said on Sunday morning that it had observed three dozen PLA planes, seven navy ships and one “official” ship, which was probably the coast guard, active near the island over the past 24 hours.

Maps provided by the ministry showed up to multiple UAVs operating near Taiwan and the Japan's territory off its north-east coast, seeming to travel particularly close to Yonaguni. PLA movements there are occasional, but infrequent, and Chinese military activity in the island's ADIZ generally has been minimal in the past month.

Earlier this weekend, the ministry said Beijing had been conducting another “joint combat patrol” to “harass the airspace and sea around us”. It added the island had dispatched military assets to monitor the situation. The island documents these operations a couple of times a month as part of what Taipei says is an continuous strategic pressure.

Political Strain

Tokyo has been experiencing increased strain from Beijing since the Japanese official made her remarks, with China’s consul general in the Japanese city triggering an official complaint from Tokyo by stating that “those who interfere will face consequences”.

China then summoned the Japanese ambassador for the first occasion since 2023, and China’s defence ministry declared that any Japanese intervention would be certain to collapse.

Warning for Citizens

On Friday, China advised its people to avoid visiting Japan, leading Japan to request China to take “suitable actions”, though it did not elaborate.

Three Chinese airlines announced this weekend that tickets to Japan could be cancelled without penalty.

Adding to the tensions, China’s government on the weekend advised students to rethink education plans in Japan, citing what it described as an volatile safety situation.

Although not an outright prohibition, a significant decrease in the number of Chinese students could have a detrimental effect on academic institutions in Japan. A record 336,708 foreign nationals were studying in Japan last year, according to education statistics. They featured over 123,000 learners from China – by far the largest demographic.

Official Commentary

Earlier this weekend, 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 limited skirmish; it would likely draw in other nations, including the US, and could quickly spiral into a large-scale conflict with severe repercussions.”

Strategic Positions

The government of Taiwan says the island's residents alone determine their destiny. Officials in Tokyo have traditionally refrained from discussing the island openly when discussing such scenarios, maintaining a “strategic ambiguity” also favoured by Tokyo’s main security ally, the US.

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