China Sends Maritime Patrol Vessels to Senkaku Islands During Tensions with Tokyo

Beijing has deployed its coast guard through the waters of the Senkaku islands and military drones past remote Japan's territory as Beijing escalates strains following the Japan's leader's comments regarding Taiwan.

Patrol Operations

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

“Chinese maritime patrol unit 1307 conducted patrols within the territorial waters of the Diaoyu islands. This was a legitimate rights enforcement activity conducted by the Chinese maritime authorities to protect its sovereign claims,” the statement said.

Diplomatic Spat

China and Japan have consistently clashed around the disputed territory but the latest activity occur during an escalating political dispute after the Japan's leader, Sanae Takaichi, told parliament that if China attack the self-governing island of Taiwan it could trigger a armed reaction from Japan.

That sparked an angry response from China, which has indicated it demands a withdrawal from Takaichi.

Taiwan's Position

China claims Taiwan as its own territory and plans to incorporate it under what it describes as “unification”. It has left open the military option. Taiwan’s government and people overwhelmingly reject the idea of Beijing's control – preferring to maintain the current situation without explicitly declaring themselves independent, but pledging to protect their sovereignty if necessary.

An attack or invasion by Beijing would risk escalating into a regional or global conflict, potentially involving the United States and other partner nations including Japan, which has land just 68 miles from Taiwan.

Defense Operations

On the island, the military authorities reported this weekend that it had observed 30 Chinese military aircraft, seven navy ships and one “official” ship, which was probably the coast guard, operating around the island over the past 24 hours.

Maps provided by the ministry showed up to three drones operating near the island and the Japan's territory off its north-east coast, seeming to travel particularly close to the nearby Japanese island. Chinese military transits there are not rare, but infrequent, and Beijing's defense operations in Taiwan’s air defence identification zone generally has been minimal in the past month.

Late on Saturday, the defense officials said China had been carrying out another “combined military exercise” to “test our defensive capabilities”. It noted Taiwan had sent its own aircraft and ships to track the developments. Taiwan documents these operations a few times monthly as part of what the Taiwanese government says is an continuous strategic pressure.

Diplomatic Pressure

Tokyo has been experiencing increased strain from Beijing since the Japanese official made her comments, with Beijing's diplomatic representative in the Japanese city triggering an official complaint from Tokyo by commenting that “those who interfere will face consequences”.

China 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.

Warning for Citizens

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

Three Chinese airlines announced this weekend that flights to Tokyo could be refunded or changed for free.

In another escalation, Beijing's administration 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 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 enrolled in Japanese schools 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 accused Takaichi of staging a political stunt that was “not just dangerously provocative but fundamentally perverse”.

“A clash between Tokyo and Beijing would not be a small-scale encounter; it would likely draw in other nations, including the US, and could rapidly escalate to 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 publicly mentioning Taiwan when addressing potential conflicts, maintaining a “strategic ambiguity” also preferred by Tokyo’s main security ally, the United States.

Nevertheless, China’s ruling Communist party says the incorporation of the island with the mainland China is “unavoidable”, and casts any opposition to it as escalatory. As it moves towards being capable of military annexation, Beijing has also been escalating its non-military activity and its statements towards the island.
