China Dispatches Maritime Patrol Ships to Diaoyu Islands During Dispute with Tokyo

China has sent its maritime law enforcement through the maritime area of the Senkaku islands and military drones near remote Japan's territory as Beijing ramps up strains over the Japan's leader's remarks regarding Taiwan.

Rights Enforcement Activities

On Sunday, the China's maritime patrol stated that its vessels carried out a “lawful patrol operation” through the waters of the Diaoyu islands, which are under the control of Tokyo but also asserted as territory by China.

“China coast guard vessel 1307 formation conducted patrols 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 latest activity occur during an escalating political dispute after the Japanese prime minister, the Japanese official, addressed lawmakers that if Beijing assaults democratically ruled Taiwan it could trigger a military response from Japan.

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

Island's Stance

Beijing asserts Taiwan as its sovereign land and intends to annex it under what it describes as “unification”. It has left open the use of force. The island's administration and citizens overwhelmingly reject 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 Beijing would risk escalating into a international confrontation, possibly drawing in the US and other partner nations including Tokyo, which has territory just 110km (68 miles) from Taiwan.

Defense Operations

In Taiwan, the defence ministry 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, operating around the territory over the past 24 hours.

Maps provided by the ministry showed up to multiple UAVs operating near the island and the Japan's territory off its north-east coast, appearing to go particularly close to Yonaguni. PLA movements there are occasional, but uncommon, and Beijing's defense operations in the island's ADIZ generally has been minimal in recent weeks.

Late on Saturday, the ministry said Beijing had been conducting another “joint combat patrol” to “test our defensive capabilities”. It noted the island 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.

Political Strain

Tokyo has been experiencing increased strain from China since the Japanese official made her comments, 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 Tokyo's involvement would be certain to collapse.

Travel and Education Advisory

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

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

Adding to the tensions, China’s government on Sunday urged its citizens to “carefully reconsider” studying 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 number of Chinese students could have a negative impact on Japanese universities. A historic high of over 336,000 international students were studying in Japan last year, according to education statistics. They featured over 123,000 learners from China – by far the single biggest group.

Official Commentary

Late on Saturday, a Chinese state media editorial accused Takaichi of staging a political stunt that was “both reckless and fundamentally flawed”.

“A conflict between Japan and China would not be a limited skirmish; it would probably involve other nations, including the US, and could rapidly escalate to 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 previously avoided publicly mentioning Taiwan when addressing potential conflicts, maintaining a “strategic ambiguity” 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, Beijing has also been increasing its political operations and its statements towards Taiwan.
