China Dispatches Maritime Patrol Ships to Senkaku Islands During Tensions with Tokyo

China has sent its coast guard into the waters of the Diaoyu islands and unmanned aerial vehicles past remote Japan's territory as China ramps up tensions over the Japanese prime minister’s remarks regarding the island of Taiwan.

Patrol Operations

On Sunday, the China's maritime patrol announced that its vessels carried out a “lawful patrol operation” through the waters of the Diaoyu islands, which are administered by Japan but also claimed by Beijing.

“Chinese maritime patrol unit 1307 conducted patrols within the territorial waters of the Senkaku islands. This was a lawful patrol operation conducted by the Chinese maritime authorities to protect its sovereign claims,” the statement said.

Diplomatic Spat

China and Japan have consistently clashed around the islands but the recent developments come amid an escalating political dispute after the Japan's leader, the Japanese official, told parliament that if Beijing assaults democratically ruled Taiwan it might provoke a armed reaction from Tokyo.

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

Taiwan's Position

Beijing asserts Taiwan as its own territory and plans to incorporate it under what it terms “unification”. It has left open the military option. Taiwan’s government and citizens categorically refuse the prospect of Chinese rule – choosing to preserve the current situation without formally announcing independence, but vowing to defend themselves if necessary.

An military assault by China would risk escalating into a regional or global conflict, potentially involving the United States and other partner nations including Tokyo, which has territory just 110km (68 miles) from the island.

Military Activity

In Taiwan, 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, active near the island over the previous day.

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 not rare, but uncommon, and Beijing's defense operations in Taiwan’s air defence identification zone generally has been low in recent weeks.

Late on Saturday, the ministry said Beijing had been carrying out 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 the Taiwanese government says is an ongoing military pressure campaign.

Political Strain

Japan has been facing mounting pressure from Beijing since the Japanese official made her remarks, with China’s consul general in Osaka triggering an official complaint from Japan by commenting that “the dirty head that sticks itself out must be cut off”.

China then summoned the Japanese ambassador for the first occasion since 2023, and Beijing's military authorities declared that any Japanese intervention would be certain to collapse.

Travel and Education Advisory

Late last week, Beijing advised its people to avoid visiting Japan, leading Japan to request China to take “appropriate measures”, though it did not elaborate.

Three Chinese airlines said on Saturday that flights to Tokyo 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 negative impact on academic institutions in Japan. A record 336,708 foreign nationals 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

Earlier this weekend, a Chinese state media editorial accused Takaichi of staging 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 probably involve other powers, including the US, and could quickly spiral into a major confrontation with severe repercussions.”

Policy Standpoints

The administration in Taipei says only its people can decide its future. Officials in Tokyo have previously avoided discussing the island openly when addressing potential conflicts, maintaining a “deliberate vagueness” also preferred by Tokyo’s main security ally, the US.

Nevertheless, China’s ruling Communist party says the incorporation of the island with the People’s Republic of China is “unavoidable”, and casts any opposition to it as escalatory. As it moves towards being capable of military annexation, China has also been increasing its political operations and its statements towards the island.
