Beijing Dispatches Maritime Patrol Ships to Diaoyu Islands Amid Tensions with Japan

Beijing has deployed its maritime law enforcement through the maritime area of the Senkaku islands and unmanned aerial vehicles past remote Japanese territory as Beijing escalates strains following the Japanese prime minister’s comments regarding the island of Taiwan.

Patrol Operations

On Sunday, the Chinese coast guard announced that its ships conducted a “rights enforcement patrol” through the waters of the Senkaku, which are under the control of Japan but also claimed by China.

“Chinese maritime patrol unit 1307 performed surveillance within the territorial waters of the Senkaku islands. This was a legitimate rights enforcement activity conducted by the Chinese maritime authorities to uphold its rights and interests,” officials declared.

Bilateral Tensions

China and Japan have repeatedly faced off around the islands but the recent developments come amid an escalating political dispute after the Japan's leader, Sanae Takaichi, addressed lawmakers that if Beijing assaults democratically ruled Taiwan it might provoke a armed reaction from Japan.

That provoked a furious reaction from Beijing, which has indicated it demands a retraction from Takaichi.

Island's Stance

China claims the island as its sovereign land and intends to annex it under what it terms “reunification”. It has not ruled out the use of force. The island's administration and citizens categorically refuse the prospect of Chinese rule – choosing to preserve the status quo without explicitly declaring themselves independent, but vowing to defend themselves if necessary.

An military assault by Beijing would risk escalating into a international confrontation, potentially involving the US and other allies including Japan, which has territory just 110km (68 miles) from Taiwan.

Defense Operations

On the island, the military authorities said on Sunday morning that it had detected three dozen PLA planes, seven navy ships and one government vessel, which was probably the maritime patrol, active near the island over the past 24 hours.

Maps provided by the ministry showed up to multiple UAVs flying between the island and the Japanese islands off its north-east coast, appearing to go unusually near to Yonaguni. Chinese military transits there are not rare, but infrequent, and Beijing's defense operations in Taiwan’s air defence identification zone generally has been low in the past month.

Late on Saturday, the defense officials said Beijing had been carrying out another “joint combat patrol” 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 reports such Chinese patrols a few times monthly as part of what the Taiwanese government says is an ongoing military pressure campaign.

Political Strain

Tokyo has been experiencing increased strain from Beijing since Takaichi made her remarks, with Beijing's diplomatic representative in the Japanese city triggering an official complaint from Tokyo 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 stated that any Tokyo's involvement would be certain to collapse.

Travel and Education Advisory

Late last week, 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 tickets to Japan could be cancelled without penalty.

In another escalation, China’s government on Sunday advised students to rethink education plans in Japan, citing what it characterized as an volatile safety situation.

Although not an outright prohibition, a dramatic reduction in the population of learners from China could have a detrimental effect 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 single biggest group.

Media Response

Earlier this weekend, a official press commentary charged the Japanese official with performing a diplomatic maneuver that was “not just dangerously provocative but fundamentally perverse”.

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

Strategic Positions

The government of Taiwan says only its people can decide its future. Officials in Tokyo have previously avoided 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 incorporation of the island with the mainland China is “inevitable”, and portrays dissent as provocative. As it advances toward potential armed takeover, China has also been escalating its non-military activity and its statements towards the island.
