Beijing Sends Maritime Patrol Vessels to Senkaku Islands Amid Tensions with Japan

Beijing has sent its maritime law enforcement into the maritime area of the Senkaku islands and military drones past outlying Japan's territory as Beijing ramps up tensions over the Japanese prime minister’s comments regarding the island of Taiwan.

Rights Enforcement Activities

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

“Chinese maritime patrol unit 1307 performed surveillance within the territorial waters of the Senkaku islands. This was a lawful patrol operation undertaken by the Chinese maritime authorities to uphold its rights and interests,” officials declared.

Diplomatic Spat

Beijing and Tokyo have repeatedly faced off around the disputed territory but the latest activity come amid an escalating political dispute after the Japan's leader, Sanae Takaichi, told parliament that if China attack democratically ruled Taiwan it could trigger a military response from Japan.

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

Taiwan's Position

Beijing asserts Taiwan as its own territory and plans to incorporate it under what it describes as “reunification”. It has left open the military option. The island's administration 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 required.

An military assault by China would threaten to spiral into a international confrontation, potentially involving the US and other allies including Japan, which has territory just 110km (68 miles) from the island.

Military Activity

On the island, the defence ministry reported this weekend that it had detected 30 Chinese military aircraft, multiple naval vessels and one “official” ship, which was probably the maritime patrol, active near the island over the previous day.

Official charts released 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. Chinese military transits there are not rare, but infrequent, and Beijing's defense operations in Taiwan’s air defence identification zone generally has been low in recent weeks.

Late on Saturday, the defense officials said China had been carrying out another “combined military exercise” to “harass the airspace and sea around us”. It added Taiwan had dispatched military assets to track the developments. Taiwan documents these operations a couple of times a month as part of what the Taiwanese government says is an continuous strategic pressure.

Political Strain

Japan has been facing mounting pressure from Beijing since Takaichi made her remarks, with China’s consul general in the Japanese city prompting a formal protest from Japan by commenting that “the dirty head that sticks itself out must be cut off”.

China then called in Japan's diplomat for the first occasion since 2023, and Beijing's military authorities declared that any Tokyo's involvement would be doomed to fail.

Travel and Education Advisory

Late last week, China cautioned its citizens against travelling to Japan, prompting Tokyo to urge Beijing to take “appropriate measures”, though it did not elaborate.

Three Chinese airlines said on Saturday that flights to Tokyo could be refunded or changed for free.

In another escalation, Beijing's administration on the weekend 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 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 featured over 123,000 learners from China – by far the largest demographic.

Official Commentary

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

“A clash between Tokyo and Beijing would not be a limited skirmish; it would probably involve other powers, including the US, and could rapidly escalate to a major confrontation with severe repercussions.”

Strategic Positions

The administration in Taipei says the island's residents alone determine their destiny. Japanese leaders have traditionally refrained from discussing the island openly when addressing potential conflicts, maintaining a “strategic ambiguity” also favoured by Japan's primary defense partner, the US.

However, Beijing's governing party says the incorporation of the island with the mainland China is “unavoidable”, and portrays dissent as provocative. As it advances toward potential armed takeover, China has also been increasing its political operations and its rhetoric towards Taiwan.
