China Sends Coast Guard Ships to Diaoyu Islands During Tensions with Tokyo

Beijing has deployed its maritime law enforcement through the maritime area of the Diaoyu islands and unmanned aerial vehicles past outlying Japan's territory as China escalates tensions following the Japanese prime minister’s comments regarding Taiwan.

Patrol Operations

On Sunday, the Chinese coast guard stated that its vessels conducted a “rights enforcement patrol” through the waters of the Diaoyu islands, which are administered by Tokyo but also asserted as territory by China.

“China coast guard vessel 1307 formation conducted patrols within the territorial waters of the Diaoyu islands. This was a legitimate rights enforcement activity conducted by the China coast guard to protect its sovereign claims,” officials declared.

Bilateral Tensions

Beijing and Tokyo have repeatedly faced off around the disputed territory but the recent developments occur during an escalating political dispute after the Japan's leader, the Japanese official, addressed lawmakers that if China attack the self-governing island of Taiwan it might provoke a armed reaction from Japan.

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

Taiwan's Position

Beijing asserts the island as its sovereign land and intends to annex it under what it describes as “unification”. It has not ruled out the military option. The island's administration and people categorically refuse the idea of Beijing's control – choosing to preserve the current situation without explicitly declaring themselves independent, but vowing to defend themselves if necessary.

An military assault by China would risk escalating into a regional or global conflict, possibly drawing in the US and other partner nations including Tokyo, which has territory just 68 miles from Taiwan.

Military Activity

In Taiwan, the defence ministry said on Sunday morning that it had observed three dozen PLA planes, seven navy ships and one government vessel, which was probably the coast guard, active near the island over the previous day.

Maps provided by the ministry showed up to three drones flying between Taiwan and the Japan's territory off its northeastern shoreline, appearing to go unusually near to the nearby Japanese island. Chinese military transits there are occasional, but uncommon, and Chinese military activity in the island's ADIZ generally has been minimal in the past month.

Earlier this weekend, the defense officials said China had been conducting another “combined military exercise” to “harass the airspace and sea around us”. It added the island had sent its own aircraft and ships to monitor the situation. The island documents these operations a few times monthly as part of what the Taiwanese government says is an ongoing military pressure campaign.

Diplomatic Pressure

Tokyo has been facing mounting pressure from China since Takaichi made her remarks, with Beijing's diplomatic representative in Osaka triggering an official complaint from Japan by stating that “the dirty head that sticks itself out must be cut off”.

China then summoned the Japanese ambassador for the first occasion since 2023, and China’s defence ministry declared that any Tokyo's involvement would be certain to collapse.

Warning for Citizens

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

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

Adding to the tensions, China’s government on the weekend urged its citizens to “carefully reconsider” studying in Japan, citing what it described as an volatile safety situation.

Although not an outright prohibition, 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 studying in Japan last year, according to education statistics. They included more than 123,000 Chinese students – by far the single biggest group.

Official Commentary

Late on Saturday, a Chinese state media editorial charged the Japanese official with performing a political stunt 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 nations, including the United States, and could rapidly escalate to a large-scale conflict with unimaginable consequences.”

Strategic Positions

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

Nevertheless, Beijing's governing party says the unification of Taiwan with the mainland China is “unavoidable”, and portrays dissent as provocative. As it moves towards being capable of military annexation, Beijing has also been increasing its political operations and its rhetoric towards Taiwan.
