China Dispatches Maritime Patrol Vessels to Diaoyu Islands Amid Tensions with Tokyo

Beijing has deployed its coast guard through the waters of the Senkaku islands and military drones past remote Japan's territory as Beijing ramps up tensions following the Japanese prime minister’s remarks regarding the island of Taiwan.

Rights Enforcement Activities

This past Sunday, the Chinese coast guard stated that its vessels carried out a “lawful patrol operation” through the territorial seas of the Senkaku, which are administered by Japan but also asserted as territory by Beijing.

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

Bilateral Tensions

China and Japan have repeatedly faced off around the islands but the recent developments come amid an escalating political dispute after the Japanese prime minister, Sanae Takaichi, told parliament that if China attack the self-governing island of Taiwan it could trigger a armed reaction from Tokyo.

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

Island's Stance

China claims Taiwan as its sovereign land and plans to incorporate it under what it describes as “unification”. It has left open the use of force. The island's administration and citizens categorically refuse the idea of Beijing's control – preferring to maintain the status quo without explicitly declaring themselves independent, but vowing to defend themselves if necessary.

An attack or invasion by Beijing would threaten to spiral into a international confrontation, possibly drawing in the US and other allies including Japan, which has land just 68 miles from Taiwan.

Military Activity

On the island, the military authorities reported this weekend that it had detected 30 Chinese military aircraft, seven navy ships and one government vessel, which was probably the maritime patrol, active near the territory over the past 24 hours.

Maps provided by the ministry showed up to multiple UAVs operating near the island and the Japan's territory off its northeastern shoreline, appearing to go unusually near to Yonaguni. Chinese military transits there are not rare, but infrequent, and Chinese military activity in the island's ADIZ generally has been minimal in the past month.

Late on Saturday, the ministry said China had been conducting another “combined military exercise” to “test our defensive capabilities”. It added the island had dispatched military assets to track the developments. Taiwan documents these operations a couple of times a month as part of what the Taiwanese government says is an ongoing military pressure campaign.

Diplomatic Pressure

Japan has been facing mounting pressure from Beijing since Takaichi made her remarks, with China’s consul general in the Japanese city prompting a formal protest from Japan by stating 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 declared that any Tokyo's involvement would be certain to collapse.

Travel and Education Advisory

Late last week, China cautioned its citizens against travelling to 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 the weekend advised students to rethink education plans in Japan, citing what it described 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 Japanese universities. A historic high of over 336,000 international students were enrolled in Japanese schools last year, according to education statistics. They featured over 123,000 learners from China – by far the largest demographic.

Media Response

Earlier this weekend, a Chinese state media editorial accused Takaichi of staging a diplomatic maneuver that was “both reckless and fundamentally flawed”.

“A conflict between Japan and China would not be a limited skirmish; it would probably involve other nations, including the United States, and could quickly spiral into a large-scale conflict with severe repercussions.”

Strategic Positions

The government of Taiwan says the island's residents alone determine their destiny. Officials in Tokyo have previously avoided publicly mentioning Taiwan when addressing potential conflicts, maintaining a “deliberate vagueness” also preferred by Tokyo’s main security ally, the United States.

Nevertheless, China’s ruling Communist party says the unification of Taiwan with the People’s Republic of China is “inevitable”, and casts any opposition to it as escalatory. As it advances toward potential armed takeover, China has also been escalating its non-military activity and its statements towards the island.
