China Dispatches Coast Guard Ships to Senkaku Islands During Tensions with Japan

Beijing has deployed its maritime law enforcement through the maritime area of the Diaoyu islands and unmanned aerial vehicles near outlying Japan's territory as China escalates strains following the Japan's leader's remarks regarding the island of Taiwan.

Rights Enforcement Activities

On Sunday, the Chinese coast guard announced 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 Beijing.

“Chinese maritime patrol unit 1307 performed surveillance within the maritime jurisdiction 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.

Bilateral Tensions

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, told parliament that if China attack democratically ruled Taiwan it might provoke a military response from Japan.

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

Island's Stance

Beijing asserts Taiwan as its own territory and plans to incorporate it under what it terms “reunification”. It has left open the use of force. The island's administration and people categorically refuse the prospect of Chinese rule – choosing to preserve the current situation without explicitly declaring themselves independent, but vowing to defend themselves if necessary.

An military assault by Beijing would risk escalating into a regional or global conflict, possibly drawing in the United States and other partner nations including Japan, which has land just 110km (68 miles) from Taiwan.

Military Activity

On the island, the military authorities reported this weekend that it had detected 30 Chinese military aircraft, multiple naval vessels and one “official” ship, which was likely the coast guard, operating around the island over the previous day.

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 not rare, but uncommon, and Chinese military activity in the island's ADIZ generally has been minimal in the past month.

Earlier this weekend, the ministry said China had been carrying out another “joint combat patrol” to “test our defensive capabilities”. It noted Taiwan had dispatched military assets 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.

Political Strain

Tokyo has been experiencing increased strain from China since Takaichi made her comments, with China’s consul general in Osaka triggering an official complaint from Japan by commenting that “those who interfere will face consequences”.

China then summoned the Japanese ambassador for the first occasion since 2023, and Beijing's military authorities stated that any Japanese intervention would be doomed to fail.

Travel and Education Advisory

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

Multiple carriers from China announced this weekend that flights to Tokyo could be cancelled without penalty.

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

While the advice does not amount to a ban, a dramatic reduction 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 official data. They included more than 123,000 Chinese students – by far the largest demographic.

Media Response

Earlier this weekend, a official press commentary charged the Japanese official with performing a political stunt that was “both reckless and fundamentally flawed”.

“A conflict between Japan and China would not be a small-scale encounter; it would probably involve other nations, including the US, and could rapidly escalate to a large-scale conflict with unimaginable consequences.”

Policy Standpoints

The administration in Taipei says only its people can decide its future. Japanese leaders have traditionally refrained from discussing the island openly when discussing such scenarios, maintaining a “deliberate vagueness” also favoured by Japan's primary defense partner, the United States.

Nevertheless, China’s ruling Communist party says the incorporation of the island with the mainland China is “inevitable”, and portrays dissent as provocative. As it moves towards being capable of military annexation, China has also been increasing its political operations and its rhetoric towards Taiwan.
