China Dispatches Maritime Patrol Ships to Diaoyu Islands During Dispute with Japan

China has sent its maritime law enforcement through the maritime area of the Senkaku islands and military drones past outlying Japan's territory as China ramps up tensions following the Japan's leader's comments regarding Taiwan.

Rights Enforcement Activities

This past Sunday, the China's maritime patrol announced that its ships conducted a “rights enforcement patrol” through the waters of the Senkaku, which are administered by Tokyo but also claimed by Beijing.

“China coast guard vessel 1307 formation performed surveillance within the maritime jurisdiction of the Diaoyu islands. This was a legitimate rights enforcement activity undertaken by the Chinese maritime authorities to protect its sovereign claims,” officials declared.

Bilateral Tensions

Beijing and Tokyo have consistently clashed around the islands but the latest activity come amid an escalating political dispute after the Japan's leader, Sanae Takaichi, told parliament that if Beijing assaults democratically ruled Taiwan it could trigger a armed reaction from Japan.

That sparked an angry response from Beijing, which has indicated it demands a withdrawal from Takaichi.

Island's Stance

Beijing asserts Taiwan as its sovereign land and intends to annex it under what it terms “unification”. It has not ruled out the military option. Taiwan’s government and people overwhelmingly reject the idea of Beijing's control – preferring to maintain the status quo without formally announcing independence, but vowing to defend themselves if required.

An military assault by China would threaten to spiral into a regional or global conflict, possibly drawing in the US and other allies including Tokyo, which has land just 110km (68 miles) from the island.

Defense Operations

On the island, the military authorities reported this weekend that it had detected three dozen PLA planes, multiple naval vessels and one “official” ship, which was probably the coast guard, operating around the island over the previous day.

Maps provided by the ministry showed up to multiple UAVs operating near Taiwan and the Japanese islands off its north-east coast, appearing to go particularly close to the nearby Japanese island. Chinese military transits there are occasional, but uncommon, and Chinese military activity in Taiwan’s air defence identification zone generally has been low in recent weeks.

Late on Saturday, the defense officials said Beijing had been conducting another “combined military exercise” to “test our defensive capabilities”. It added Taiwan had dispatched military assets to monitor the situation. The island reports such Chinese patrols a few times monthly 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 prompting a formal protest from Tokyo by commenting that “those who interfere will face consequences”.

China then summoned the Japanese ambassador for the first occasion since 2023, and China’s defence ministry stated that any Tokyo's involvement 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 did not elaborate.

Three Chinese airlines said on Saturday that tickets to Japan could be refunded or changed for free.

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

Although not an outright prohibition, a significant decrease in the number of Chinese students could have a detrimental effect on academic institutions in Japan. A record 336,708 foreign nationals were studying in Japan last year, according to education statistics. They included more than 123,000 Chinese students – by far the single biggest group.

Media Response

Late on Saturday, a official press commentary accused Takaichi of staging a political stunt that was “both reckless and fundamentally flawed”.

“A conflict between Japan and China 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 unimaginable consequences.”

Policy Standpoints

The government of Taiwan says only its people can decide its future. Japanese leaders have previously avoided discussing the island openly when addressing potential conflicts, maintaining a “deliberate vagueness” also preferred by Tokyo’s main security ally, the United States.

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 advances toward potential armed takeover, Beijing has also been escalating its non-military activity and its statements towards Taiwan.
