Beijing Sends Maritime Patrol Ships to Diaoyu Islands Amid Dispute with Japan

Beijing has sent its maritime law enforcement into the waters of the Diaoyu islands and military drones past remote Japanese territory as China ramps up tensions over the Japanese prime minister’s comments regarding Taiwan.

Rights Enforcement Activities

This past Sunday, the Chinese coast guard stated that its ships conducted a “rights enforcement patrol” through the waters of the Diaoyu islands, which are administered by Japan but also claimed 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 conducted by the China coast guard to protect its sovereign claims,” officials declared.

Diplomatic Spat

China and Japan have repeatedly faced off around the islands but the latest activity come amid an intensifying diplomatic spat after the Japanese prime minister, the Japanese official, addressed lawmakers that if Beijing assaults democratically ruled Taiwan it could trigger a military response from Japan.

That provoked a furious reaction from China, which has indicated it demands a withdrawal from Takaichi.

Taiwan's Position

Beijing asserts the island as its sovereign land and intends to annex it under what it terms “reunification”. It has left open the military option. Taiwan’s government and people overwhelmingly reject the prospect of Chinese rule – choosing to preserve the status quo without formally announcing independence, but vowing to defend themselves if necessary.

An attack or invasion by Beijing would threaten to spiral into a international confrontation, possibly drawing in the US and other allies including Japan, which has territory just 68 miles from Taiwan.

Military Activity

On the island, the defence ministry said on Sunday morning that it had detected three dozen PLA planes, multiple naval vessels and one government vessel, which was probably the coast guard, active near the island over the past 24 hours.

Maps provided by the ministry showed up to three drones operating near the island and the Japan's territory off its northeastern shoreline, appearing to go unusually near to the nearby Japanese island. PLA movements there are not rare, but uncommon, and Beijing's defense operations in the island's ADIZ generally has been minimal in recent weeks.

Earlier this weekend, the ministry said China had been carrying out 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. Taiwan reports such Chinese patrols a couple of times a month as part of what Taipei says is an ongoing military pressure campaign.

Diplomatic Pressure

Tokyo has been facing mounting pressure 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 “those who interfere will face consequences”.

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 doomed to fail.

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.

Multiple carriers from China said on Saturday that tickets to Japan could be cancelled without penalty.

In another escalation, Beijing's administration on the weekend urged its citizens to “carefully reconsider” studying in Japan, citing what it characterized as an volatile safety situation.

While the advice does not amount to a ban, a dramatic reduction in the population of learners from China could have a negative impact on Japanese universities. A historic high of over 336,000 international students were enrolled in Japanese schools 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 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 quickly spiral into 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 publicly mentioning Taiwan when addressing potential conflicts, maintaining a “strategic ambiguity” also favoured by Japan's primary defense partner, the US.

However, 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, Beijing has also been increasing its political operations and its rhetoric towards the island.
