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

Beijing has sent its coast guard into the waters of the Diaoyu islands and military drones near remote Japanese territory as Beijing escalates strains over the Japan's leader's remarks regarding the island of Taiwan.

Rights Enforcement Activities

On Sunday, the China's maritime patrol announced that its vessels carried out a “rights enforcement patrol” through the waters of the Diaoyu islands, which are administered by Tokyo but also asserted as territory by China.

“Chinese maritime patrol unit 1307 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,” officials declared.

Bilateral Tensions

China and Japan have consistently clashed around the disputed territory but the recent developments come amid an escalating political dispute after the Japanese prime minister, Sanae Takaichi, told parliament that if China attack democratically ruled Taiwan it could trigger a armed reaction from Tokyo.

That provoked a furious reaction from Beijing, which has indicated it demands a retraction from Takaichi.

Taiwan's Position

Beijing asserts the island as its sovereign land and plans to incorporate it under what it describes as “unification”. It has left open the military option. The island's administration and citizens categorically refuse the idea of Beijing's control – preferring to maintain the current situation without formally announcing independence, but pledging to protect their sovereignty if necessary.

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

Defense Operations

On the island, the military authorities reported this weekend that it had detected 30 Chinese military aircraft, multiple naval vessels and one “official” ship, which was likely the maritime patrol, active near the island over the past 24 hours.

Maps provided by the ministry showed up to three drones operating near Taiwan and the Japanese islands off its north-east coast, seeming to travel particularly close to the nearby Japanese island. Chinese military transits there are occasional, but uncommon, and Chinese military activity in the island's ADIZ generally has been minimal in recent weeks.

Late on Saturday, the ministry said China had been conducting another “combined military exercise” to “harass the airspace and sea around us”. It added Taiwan had dispatched military assets to track the developments. The island reports such Chinese patrols a few times monthly as part of what Taipei says is an ongoing military pressure campaign.

Diplomatic Pressure

Japan has been facing mounting pressure from Beijing since Takaichi made her remarks, with Beijing's diplomatic representative in Osaka prompting a formal protest from Japan by stating 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 declared that any Japanese intervention would be certain to collapse.

Travel and Education Advisory

Late last week, China advised its people to avoid visiting Japan, leading Japan to request China to take “suitable actions”, though it provided no details.

Multiple carriers from China announced this weekend that tickets to Japan could be cancelled without penalty.

In another escalation, China’s government on Sunday urged its citizens to “carefully reconsider” studying 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 population of learners from China could have a detrimental effect on Japanese universities. A historic high of over 336,000 international students were studying in Japan last year, according to education statistics. They included more than 123,000 Chinese students – by far the single biggest group.

Media Response

Earlier this weekend, a Chinese state media editorial accused Takaichi of staging 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 probably involve other nations, including the United States, and could quickly spiral into a major confrontation with unimaginable consequences.”

Strategic Positions

The administration in Taipei says only its people can decide its future. Japanese leaders have previously avoided publicly mentioning Taiwan when addressing potential conflicts, maintaining a “strategic ambiguity” also favoured by Japan's primary defense partner, the United States.

However, Beijing's governing party says the unification of Taiwan with the mainland China is “inevitable”, and portrays dissent as provocative. As it moves towards being capable of military annexation, China has also been escalating its non-military activity and its statements towards the island.
