China Dispatches Maritime Patrol Vessels to Diaoyu Islands During Tensions with Japan

Beijing has sent its coast guard through the waters of the Senkaku islands and military drones near outlying Japanese territory as Beijing escalates tensions over the Japanese prime minister’s remarks regarding Taiwan.

Patrol Operations

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

“Chinese maritime patrol unit 1307 conducted patrols within the territorial waters of the Senkaku islands. This was a legitimate rights enforcement activity undertaken 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 latest activity occur during an intensifying diplomatic spat after the Japan's leader, Sanae Takaichi, 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 signalled it expects a withdrawal from Takaichi.

Island's Stance

Beijing asserts Taiwan as its own territory and intends to annex it under what it describes as “unification”. It has not ruled out the military option. The island's administration and citizens categorically refuse the prospect of Chinese rule – preferring to maintain the current situation without formally announcing independence, but vowing to defend themselves if necessary.

An attack or invasion by Beijing would risk escalating into a international confrontation, potentially involving the US and other allies including Tokyo, which has land just 68 miles from Taiwan.

Military Activity

On the island, the military authorities reported this weekend that it had observed 30 Chinese military aircraft, seven navy ships and one “official” ship, which was likely the coast guard, active near the island over the past 24 hours.

Official charts released showed up to three drones flying between Taiwan and the Japan's territory off its northeastern shoreline, seeming to travel particularly close to Yonaguni. PLA movements there are occasional, but uncommon, and Chinese military activity in the island's ADIZ generally has been low in recent weeks.

Earlier this weekend, the defense officials said China had been carrying out another “combined military exercise” to “test our defensive capabilities”. It noted the island had dispatched military assets to monitor the situation. Taiwan reports such Chinese patrols a couple of times a month as part of what the Taiwanese government says is an continuous strategic pressure.

Diplomatic Pressure

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

Beijing then summoned the Japanese ambassador for the first occasion since 2023, and Beijing's military authorities declared that any Japanese intervention would be certain to collapse.

Warning for Citizens

On Friday, 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 tickets to Japan could be refunded or changed for free.

Adding to the tensions, China’s government on the weekend advised students to rethink education plans 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 record 336,708 foreign nationals 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

Late on Saturday, a official press commentary charged the Japanese official with performing a political stunt that was “both reckless and fundamentally flawed”.

“A clash between Tokyo and Beijing would not be a small-scale encounter; it would probably involve other nations, including the US, and could quickly spiral into a large-scale conflict with unimaginable consequences.”

Strategic Positions

The government of Taiwan says the island's residents alone determine their destiny. Officials in Tokyo have previously avoided publicly mentioning Taiwan when discussing such scenarios, maintaining a “deliberate vagueness” also favoured by Japan's primary defense partner, the US.

However, Beijing's governing party says the incorporation of the island with the People’s Republic of China is “inevitable”, and portrays dissent as provocative. As it advances toward potential armed takeover, Beijing has also been increasing its political operations and its rhetoric towards the island.
