China Sends Coast Guard Vessels to Senkaku Islands During Tensions with Tokyo

Beijing has deployed its coast guard through the maritime area of the Senkaku islands and military drones past outlying Japanese territory as Beijing ramps up strains over the Japan's leader's remarks regarding Taiwan.

Patrol Operations

This past Sunday, the China's maritime patrol stated that its vessels carried out a “lawful patrol operation” through the territorial seas of the Diaoyu islands, which are under the control of Tokyo but also claimed by China.

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

Bilateral Tensions

Beijing and Tokyo have consistently clashed around the disputed territory but the recent developments occur during an intensifying diplomatic spat after the Japan's leader, Sanae Takaichi, told parliament that if Beijing assaults democratically ruled Taiwan it might provoke a military response from Tokyo.

That provoked a furious reaction from Beijing, which has signalled it expects a withdrawal from Takaichi.

Taiwan's Position

China claims the island as its own territory and plans to incorporate it under what it terms “unification”. It has not ruled out the military option. Taiwan’s government and citizens categorically refuse the idea of Beijing's control – choosing to preserve the status quo without formally announcing independence, but pledging to protect their sovereignty if required.

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 Tokyo, which has land just 68 miles from Taiwan.

Defense Operations

In Taiwan, the military authorities said on Sunday morning that it had observed three dozen PLA planes, multiple naval vessels and one “official” ship, which was likely the coast guard, operating around the territory over the past 24 hours.

Maps provided by the ministry showed up to three drones flying between the island and the Japanese islands off its northeastern shoreline, appearing to go particularly close to Yonaguni. Chinese military transits there are not rare, but uncommon, and Chinese military activity in Taiwan’s air defence identification zone generally has been minimal in recent weeks.

Late on Saturday, the defense officials said Beijing had been conducting another “joint combat patrol” to “harass the airspace and sea around us”. It noted Taiwan had sent its own aircraft and ships to track the developments. The island reports such Chinese patrols a few times monthly as part of what the Taiwanese government says is an ongoing military pressure campaign.

Diplomatic Pressure

Tokyo has been experiencing increased strain from Beijing 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 declared that any Japanese intervention would be certain to collapse.

Warning for Citizens

Late last week, China advised its people to avoid visiting Japan, prompting Tokyo to urge Beijing to take “appropriate measures”, though it provided no details.

Three Chinese airlines announced this weekend that tickets to Japan could be cancelled without penalty.

Adding to the tensions, Beijing's administration on Sunday advised students to rethink education plans in Japan, citing what it described as an volatile safety situation.

Although not an outright prohibition, a dramatic reduction in the number of Chinese students could have a detrimental effect on academic institutions in Japan. A record 336,708 foreign nationals 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

Late on Saturday, a official press commentary 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 powers, including the United States, and could rapidly escalate to a major confrontation with unimaginable consequences.”

Strategic Positions

The government of Taiwan says only its people can decide its future. Japanese leaders have previously avoided publicly mentioning Taiwan when discussing such scenarios, maintaining a “deliberate vagueness” also favoured by Tokyo’s main security ally, the US.

However, Beijing's governing party says the unification of Taiwan with the People’s Republic of China is “unavoidable”, and casts any opposition to it as escalatory. As it advances toward potential armed takeover, China has also been increasing its political operations and its rhetoric towards Taiwan.
