China Sends Maritime Patrol Vessels to Senkaku Islands During Tensions with Tokyo

China has deployed its coast guard through the waters of the Senkaku islands and unmanned aerial vehicles past remote Japanese territory as Beijing escalates strains over the Japan's leader's comments regarding the island of Taiwan.

Rights Enforcement Activities

On Sunday, the China's maritime patrol stated that its vessels conducted a “rights enforcement patrol” through the territorial seas of the Senkaku, which are administered by Japan but also claimed by China.

“China coast guard vessel 1307 formation performed surveillance within the maritime jurisdiction of the Diaoyu islands. This was a legitimate rights enforcement activity undertaken by the Chinese maritime authorities to uphold its rights and interests,” the statement said.

Diplomatic Spat

Beijing and Tokyo have repeatedly faced off around the disputed territory but the recent developments occur during an intensifying diplomatic spat after the Japanese prime minister, Sanae Takaichi, addressed lawmakers that if China attack the self-governing island of Taiwan it might provoke a armed reaction from Japan.

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

Taiwan's Position

China claims Taiwan as its own territory and intends to annex it under what it terms “unification”. It has not ruled out the military option. Taiwan’s government and people overwhelmingly reject the idea of Beijing's control – preferring to maintain the status quo without formally announcing independence, but vowing to defend themselves if required.

An military assault by Beijing would risk escalating into a international confrontation, potentially involving the United States and other allies including Tokyo, which has territory just 68 miles from Taiwan.

Defense Operations

In Taiwan, the military authorities reported this weekend that it had observed three dozen PLA planes, multiple naval vessels and one government vessel, which was probably the coast guard, operating around the territory over the previous day.

Official charts released showed up to three drones flying between the island and the Japan's territory off its north-east coast, appearing to go particularly close to Yonaguni. PLA movements there are not rare, but uncommon, and Beijing's defense operations in Taiwan’s air defence identification zone generally has been low in the past month.

Late on Saturday, the ministry said China had been carrying out another “joint combat patrol” to “test our defensive capabilities”. It noted 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.

Political Strain

Tokyo has been facing mounting pressure from China since Takaichi made her remarks, with China’s consul general in Osaka 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 stated that any Tokyo's involvement would be doomed to fail.

Travel and Education Advisory

Late last week, China cautioned its citizens against travelling to Japan, leading Japan to request China to take “suitable actions”, though it did not elaborate.

Three Chinese airlines said on Saturday that tickets to Japan could be cancelled without penalty.

Adding to the tensions, Beijing's administration on Sunday urged its citizens to “carefully reconsider” studying 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 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 single biggest group.

Official Commentary

Earlier this weekend, 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 small-scale encounter; it would likely draw in other nations, including the United States, and could quickly spiral into a large-scale conflict with unimaginable consequences.”

Policy Standpoints

The government of Taiwan says only its people can decide its future. Japanese leaders 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 incorporation of the island with the People’s Republic of China is “unavoidable”, and casts any opposition to it as escalatory. As it advances toward potential armed takeover, Beijing has also been increasing its political operations and its rhetoric towards the island.
