Beijing Dispatches Maritime Patrol Ships to Diaoyu Islands During Tensions with Tokyo

Beijing has sent its coast guard through the maritime area of the Senkaku islands and military drones near remote Japan's territory as China escalates tensions over the Japan's leader's remarks regarding Taiwan.

Rights Enforcement Activities

This past Sunday, the Chinese coast guard stated that its ships carried out a “rights enforcement patrol” through the territorial seas of the Diaoyu islands, which are administered by Tokyo but also asserted as territory by China.

“China coast guard vessel 1307 formation performed surveillance within the territorial waters of the Senkaku islands. This was a lawful patrol operation conducted by the China coast guard to uphold its rights and interests,” the statement said.

Bilateral Tensions

China and Japan have repeatedly faced off around the disputed territory but the latest activity occur during an escalating political dispute after the Japanese prime minister, Sanae Takaichi, addressed lawmakers that if China attack the self-governing island of Taiwan it could trigger a armed reaction from Japan.

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

Taiwan's Position

China claims the island as its sovereign land and intends to annex it under what it describes as “reunification”. It has left open the use of force. Taiwan’s government and people 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 attack or invasion by Beijing would risk escalating into a international confrontation, possibly drawing in the US and other partner nations including Japan, which has territory just 68 miles from Taiwan.

Military Activity

In Taiwan, the military authorities said on Sunday morning that it had observed three dozen PLA planes, multiple naval vessels and one government vessel, which was likely the maritime patrol, active near the territory over the previous day.

Maps provided by the ministry showed up to multiple UAVs flying between Taiwan and the Japan's territory off its northeastern shoreline, appearing to go particularly close to Yonaguni. Chinese military transits there are occasional, but infrequent, and Beijing's defense operations in Taiwan’s air defence identification zone generally has been low in recent weeks.

Late on Saturday, the defense officials said China had been conducting another “joint combat patrol” to “test our defensive capabilities”. It noted the island had dispatched military assets to track the developments. The island reports such Chinese patrols a few times monthly as part of what Taipei says is an ongoing military pressure campaign.

Political Strain

Japan has been facing mounting pressure from Beijing since Takaichi made her remarks, with China’s consul general in the Japanese city triggering an official complaint from Tokyo by stating that “those who interfere will face consequences”.

Beijing then called in Japan's diplomat for the first occasion since 2023, and China’s defence ministry declared that any Japanese intervention would be certain to collapse.

Warning for Citizens

On Friday, 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 refunded or changed for free.

Adding to the tensions, China’s government on Sunday urged its citizens to “carefully reconsider” studying in Japan, citing what it described 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 Japanese universities. A historic high of over 336,000 international students were studying in Japan last year, according to education statistics. They featured over 123,000 learners from China – by far the single biggest group.

Media Response

Late on Saturday, a Chinese state media editorial charged the Japanese official with performing 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 probably involve other nations, including the US, and could rapidly escalate to a major confrontation with unimaginable consequences.”

Policy Standpoints

The government of Taiwan says only its people can decide its future. Officials in Tokyo have previously avoided publicly mentioning Taiwan when discussing such scenarios, maintaining a “deliberate vagueness” also favoured by Tokyo’s main security ally, the United States.

However, China’s ruling Communist party says the unification of Taiwan 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 rhetoric towards the island.
