Beijing has deployed its maritime law enforcement into the waters of the Senkaku islands and military drones past remote Japanese territory as China ramps up strains following the Japan's leader's comments regarding Taiwan.
On Sunday, the China's maritime patrol stated that its vessels carried out a “rights enforcement patrol” through the waters of the Diaoyu islands, which are under the control of 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 lawful patrol operation conducted by the Chinese maritime authorities to protect its sovereign claims,” the statement said.
Beijing and Tokyo have repeatedly faced off around the disputed territory but the recent developments come amid an intensifying diplomatic spat after the Japanese prime minister, Sanae Takaichi, addressed lawmakers that if Beijing assaults the self-governing island of Taiwan it could trigger a military response from Tokyo.
That provoked a furious reaction from China, which has indicated it demands a retraction from Takaichi.
China claims the island as its own territory and plans to incorporate it under what it describes as “unification”. It has left open the military option. Taiwan’s government and people categorically refuse the prospect of Chinese rule – preferring to maintain the current situation without explicitly declaring themselves independent, but vowing to defend themselves if required.
An military assault by China would threaten to spiral into a regional or global conflict, potentially involving the United States and other partner nations including Tokyo, which has territory just 68 miles from Taiwan.
In Taiwan, the military authorities said on Sunday morning that it had detected three dozen PLA planes, seven navy ships and one government vessel, which was likely the maritime patrol, 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 unusually near to Yonaguni. Chinese military transits there are not rare, but infrequent, and Beijing's defense operations in the island's ADIZ generally has been low in recent weeks.
Late on Saturday, the defense officials said Beijing 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 couple of times a month as part of what the Taiwanese government says is an ongoing military pressure campaign.
Japan has been experiencing increased strain from China since the Japanese official made her remarks, with China’s consul general in Osaka prompting a formal protest from Tokyo by stating that “the dirty head that sticks itself out must be cut off”.
Beijing then summoned the Japanese ambassador for the first occasion since 2023, and Beijing's military authorities declared that any Tokyo's involvement would be certain to collapse.
On Friday, Beijing advised its people to avoid visiting Japan, leading Japan to request China to take “suitable actions”, though it provided no details.
Multiple carriers from China announced this weekend that flights to Tokyo could be refunded or changed for free.
Adding to the tensions, China’s government on Sunday advised students to rethink education plans in Japan, citing what it described as an unstable security environment.
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 enrolled in Japanese schools last year, according to official data. They included more than 123,000 Chinese students – by far the single biggest group.
Earlier this weekend, a official press commentary charged the Japanese official with performing a political stunt that was “not just dangerously provocative but fundamentally perverse”.
“A conflict between Japan and China would not be a small-scale encounter; it would likely draw in other nations, including the US, and could rapidly escalate to a major confrontation with severe repercussions.”
The administration in Taipei says the island's residents alone determine their destiny. Officials in Tokyo have traditionally refrained from publicly mentioning Taiwan 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 unification of Taiwan with the People’s Republic of China is “inevitable”, and casts any opposition to it as escalatory. As it advances toward potential armed takeover, Beijing has also been escalating its non-military activity and its rhetoric towards Taiwan.
