Beijing Dispatches Coast Guard Vessels to Diaoyu Islands Amid Dispute with Japan

Beijing has sent its coast guard into the waters of the Diaoyu islands and military drones near remote Japan's territory as China ramps up strains following the Japan's leader's remarks regarding the island of Taiwan.

Patrol Operations

This past Sunday, the Chinese coast guard stated that its vessels carried out a “rights enforcement patrol” through the territorial seas of the Senkaku, which are under the control of Tokyo but also asserted as territory by Beijing.

“Chinese maritime patrol unit 1307 performed surveillance within the maritime jurisdiction of the Diaoyu islands. This was a lawful patrol operation undertaken by the Chinese maritime authorities to uphold its rights and interests,” officials declared.

Bilateral Tensions

Beijing and Tokyo have repeatedly faced off around the disputed territory but the recent developments occur during an intensifying diplomatic spat after the Japan's leader, Sanae Takaichi, told parliament that if China attack democratically ruled Taiwan it might provoke a military response from Japan.

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

Island's Stance

China claims Taiwan as its sovereign land and plans to incorporate it under what it describes as “reunification”. It has left open the use of force. Taiwan’s government and citizens categorically refuse the idea of Beijing's control – preferring to maintain the current situation without formally announcing independence, but vowing to defend themselves if necessary.

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

Military Activity

On the island, the defence ministry said on Sunday morning that it had detected 30 Chinese military aircraft, seven navy ships and one government vessel, which was probably the maritime patrol, operating around the territory over the previous day.

Official charts released showed up to multiple UAVs flying between Taiwan and the Japan's territory off its north-east coast, seeming to travel unusually near to the nearby Japanese island. Chinese military transits there are occasional, but uncommon, and Beijing's defense operations in Taiwan’s air defence identification zone generally has been minimal in recent weeks.

Late on Saturday, the ministry said Beijing had been conducting another “combined military exercise” to “test our defensive capabilities”. 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.

Diplomatic Pressure

Japan has been experiencing increased strain from China since Takaichi made her remarks, with Beijing's diplomatic representative in Osaka triggering an official complaint from Japan by commenting that “those who interfere will face consequences”.

China then called in Japan's diplomat for the first occasion since 2023, and Beijing's military authorities stated that any Tokyo's involvement would be doomed to fail.

Warning for Citizens

Late last week, China cautioned its citizens against travelling to Japan, leading Japan to request China to take “appropriate measures”, though it provided no details.

Multiple carriers from China announced this weekend that flights to Tokyo could be cancelled without penalty.

In another escalation, Beijing's administration on the weekend urged its citizens to “carefully reconsider” studying in Japan, citing what it characterized as an unstable security environment.

While the advice does not amount to a ban, a significant decrease in the number of Chinese students 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 education statistics. They included more than 123,000 Chinese students – by far the largest demographic.

Media Response

Late on Saturday, a Chinese state media editorial 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 limited skirmish; it would likely draw in other powers, including the United States, and could rapidly escalate to a large-scale conflict with unimaginable consequences.”

Strategic Positions

The administration in Taipei says the island's residents alone determine their destiny. Officials in Tokyo have previously avoided discussing the island openly when addressing potential conflicts, maintaining a “strategic ambiguity” also favoured by Tokyo’s main security ally, the US.

Nevertheless, Beijing's governing party says the incorporation of the island with the People’s Republic of China is “inevitable”, and casts any opposition to it as escalatory. As it moves towards being capable of military annexation, Beijing has also been escalating its non-military activity and its statements towards Taiwan.
