China Sends Coast Guard Ships to Diaoyu Islands During Dispute with Japan

Beijing has deployed its coast guard through the maritime area of the Diaoyu islands and unmanned aerial vehicles near remote Japan's territory as Beijing ramps up tensions following the Japanese prime minister’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 under the control of Tokyo but also asserted as territory by Beijing.

“China coast guard vessel 1307 formation performed surveillance within the territorial waters of the Senkaku islands. This was a lawful patrol operation undertaken 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 disputed territory but the recent developments occur during an intensifying diplomatic spat after the Japan's leader, the Japanese official, told parliament that if China attack democratically ruled Taiwan it could trigger a military response from Japan.

That provoked a furious reaction from Beijing, which has signalled it expects a withdrawal from Takaichi.

Island's Stance

China claims Taiwan as its sovereign land and intends to annex it under what it describes as “reunification”. It has left open the use of force. The island's administration and people categorically refuse the idea of Beijing's control – choosing to preserve the status quo without explicitly declaring themselves independent, but pledging to protect their sovereignty if required.

An attack or invasion by China 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.

Military Activity

On the island, the defence ministry said on Sunday morning that it had observed three dozen PLA planes, seven navy ships and one government vessel, which was probably the maritime patrol, operating around the island over the previous day.

Maps provided by the ministry showed up to three drones operating near Taiwan and the Japan's territory off its north-east coast, appearing to go unusually near to the nearby Japanese island. PLA movements there are occasional, but infrequent, and Chinese military activity in the island's ADIZ generally has been low in the past month.

Late on Saturday, the ministry said China had been conducting another “joint combat patrol” 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 continuous strategic pressure.

Diplomatic Pressure

Japan has been facing mounting pressure from Beijing since Takaichi made her remarks, with China’s consul general in Osaka triggering an official complaint from Tokyo by commenting that “the dirty head that sticks itself out must be cut off”.

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

Warning for Citizens

On Friday, Beijing advised its people to avoid visiting Japan, prompting Tokyo to urge Beijing to take “suitable actions”, though it did not elaborate.

Three Chinese airlines announced this weekend that flights to Tokyo could be cancelled without penalty.

Adding to the tensions, 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 significant decrease in the population of learners from China 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 featured over 123,000 learners from China – by far the single biggest group.

Media Response

Earlier this weekend, a Chinese state media editorial charged the Japanese official with performing a diplomatic maneuver that was “not just dangerously provocative but fundamentally perverse”.

“A conflict between Japan and China would not be a small-scale encounter; it would likely draw in other powers, including the US, and could quickly spiral into a major confrontation with unimaginable consequences.”

Strategic Positions

The government of Taiwan says only its people can decide its future. Japanese leaders have previously avoided publicly mentioning Taiwan when discussing such scenarios, maintaining a “deliberate vagueness” also preferred by Tokyo’s main security ally, the United States.

However, Beijing's governing party says the incorporation of the island 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 statements towards Taiwan.
