Beijing Dispatches Maritime Patrol Vessels to Senkaku Islands During Dispute with Tokyo

Beijing has deployed its maritime law enforcement into the maritime area of the Senkaku islands and military drones near remote Japan's territory as Beijing escalates tensions over the Japan's leader's comments regarding Taiwan.

Rights Enforcement Activities

This past Sunday, the Chinese coast guard stated that its vessels carried out a “lawful patrol operation” through the waters of the Diaoyu islands, which are under the control of Japan but also asserted as territory by Beijing.

“Chinese maritime patrol unit 1307 performed surveillance within the territorial waters of the Senkaku islands. This was a lawful patrol operation undertaken by the China coast guard to protect its sovereign claims,” officials declared.

Bilateral Tensions

China and Japan have consistently clashed around the islands but the recent developments occur during an intensifying diplomatic spat after the Japanese prime minister, Sanae Takaichi, told parliament that if Beijing assaults democratically ruled Taiwan it could trigger a military response from Japan.

That sparked an angry response from China, which has signalled it expects a withdrawal from the Japanese official.

Taiwan's Position

China claims Taiwan as its own territory and plans to incorporate it under what it terms “reunification”. 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 necessary.

An attack or invasion by China would risk escalating into a regional or global conflict, possibly drawing in the US and other partner nations including Tokyo, which has territory just 68 miles from Taiwan.

Defense Operations

On the island, the defence ministry reported this weekend that it had detected three dozen PLA planes, multiple naval vessels and one government vessel, which was probably the coast guard, operating around the island over the past 24 hours.

Maps provided by the ministry showed up to three drones flying between Taiwan and the Japanese islands off its northeastern shoreline, appearing to go unusually near to the nearby Japanese island. Chinese military transits there are occasional, but infrequent, and Chinese military activity in Taiwan’s air defence identification zone generally has been minimal in the past month.

Late on Saturday, the defense officials said Beijing had been conducting another “combined military exercise” to “test our defensive capabilities”. It added Taiwan had sent its own aircraft and ships 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 experiencing increased strain from China since the Japanese official made her remarks, with Beijing's diplomatic representative in Osaka prompting a formal protest from Japan by commenting 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 stated that any Japanese intervention would be certain to collapse.

Travel and Education Advisory

On Friday, China cautioned its citizens against travelling to Japan, prompting Tokyo to urge Beijing to take “suitable actions”, though it did not elaborate.

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

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

While the advice does not amount to a ban, 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 studying in Japan last year, according to official data. They included more than 123,000 Chinese students – by far the single biggest group.

Media Response

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

“A clash between Tokyo and Beijing would not be a small-scale encounter; it would likely draw in other nations, including the United States, and could rapidly escalate to a major confrontation with unimaginable consequences.”

Strategic Positions

The administration in Taipei says the island's residents alone determine their destiny. Japanese leaders have traditionally refrained from publicly mentioning Taiwan when discussing such scenarios, maintaining a “deliberate vagueness” also preferred by Tokyo’s main security ally, the United States.

However, Beijing's governing party says the incorporation of the island with the People’s Republic of China is “unavoidable”, 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.
