China Sends Coast Guard Ships to Senkaku Islands Amid Tensions with Japan

Beijing has deployed its coast guard through the maritime area of the Senkaku islands and military drones near outlying Japanese territory as Beijing escalates tensions following the Japanese prime minister’s remarks regarding the island of Taiwan.

Rights Enforcement Activities

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

“China coast guard vessel 1307 formation conducted patrols within the territorial waters of the Senkaku islands. This was a legitimate rights enforcement activity undertaken by the Chinese maritime authorities to uphold its rights and interests,” officials declared.

Diplomatic Spat

China and Japan have consistently clashed around the disputed territory but the recent developments come amid an escalating political dispute after the Japan's leader, Sanae Takaichi, addressed lawmakers that if Beijing assaults the self-governing island of Taiwan it could trigger a armed reaction from Tokyo.

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

Island's Stance

Beijing asserts 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 categorically refuse the prospect of Chinese rule – preferring to maintain the status quo without formally announcing independence, but pledging to protect their sovereignty if required.

An attack or invasion by China would risk escalating into a international confrontation, possibly drawing in the United States and other allies including Tokyo, which has territory just 68 miles from the island.

Military Activity

In Taiwan, the defence ministry reported this weekend that it had detected three dozen PLA planes, seven navy ships and one “official” ship, which was likely the maritime patrol, operating around the territory over the past 24 hours.

Official charts released showed up to three drones operating near the island and the Japanese islands off its north-east coast, appearing to go particularly close to Yonaguni. PLA movements there are not rare, but infrequent, and Chinese military activity in Taiwan’s air defence identification zone generally has been low in the past month.

Earlier this weekend, the ministry said China had been conducting another “joint combat patrol” to “test our defensive capabilities”. It noted Taiwan had dispatched military assets to track the developments. The island documents these operations a few times monthly as part of what Taipei says is an continuous strategic pressure.

Diplomatic Pressure

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 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 China’s defence ministry stated that any Japanese intervention would be doomed to fail.

Warning for Citizens

On Friday, China 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 refunded or changed for free.

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 population of learners from China could have a detrimental effect on academic institutions in Japan. A record 336,708 foreign nationals were enrolled in Japanese schools last year, according to education statistics. They featured over 123,000 learners from China – by far the largest demographic.

Media Response

Earlier this weekend, a Chinese state media editorial charged the Japanese official with performing a diplomatic maneuver that was “both reckless and fundamentally flawed”.

“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 quickly spiral into a major confrontation with unimaginable consequences.”

Strategic Positions

The administration in Taipei says only its people can decide its future. Officials in Tokyo have traditionally refrained from discussing the island openly when discussing such scenarios, maintaining a “deliberate vagueness” also favoured by Tokyo’s main security ally, the US.

Nevertheless, China’s ruling Communist party says the unification of Taiwan with the People’s Republic of China is “unavoidable”, and portrays dissent as provocative. As it advances toward potential armed takeover, Beijing has also been escalating its non-military activity and its statements towards the island.
