Beijing Sends Coast Guard Vessels to Diaoyu Islands Amid Tensions with Tokyo

Beijing has sent its maritime law enforcement into the maritime area of the Senkaku islands and unmanned aerial vehicles past outlying Japan's territory as Beijing ramps up tensions over the Japan's leader's remarks regarding Taiwan.

Patrol Operations

On Sunday, the China's maritime patrol announced that its ships conducted a “rights enforcement patrol” through the waters of the Senkaku, which are under the control of Japan but also claimed by China.

“Chinese maritime patrol unit 1307 performed surveillance within the territorial waters of the Senkaku islands. This was a legitimate rights enforcement activity conducted by the China coast guard to protect its sovereign claims,” the statement said.

Bilateral Tensions

China and Japan have repeatedly faced off around the disputed territory but the latest activity occur during an escalating political dispute after the Japanese prime minister, the Japanese official, addressed lawmakers that if Beijing assaults democratically ruled Taiwan it could trigger a military response from Japan.

That provoked a furious reaction from Beijing, which has indicated it demands a withdrawal from Takaichi.

Taiwan's Position

Beijing asserts the island as its sovereign land and plans to incorporate it under what it describes as “unification”. It has left open the use of force. Taiwan’s government and people overwhelmingly reject the idea of Beijing's control – preferring to maintain the status quo without explicitly declaring themselves independent, but pledging to protect their sovereignty if necessary.

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

Military Activity

On the island, the defence ministry said on Sunday morning that it had observed 30 Chinese military aircraft, multiple naval vessels and one “official” ship, which was likely the coast guard, active near the island over the past 24 hours.

Official charts released showed up to three drones operating near the island and the Japan's territory off its north-east coast, seeming to travel particularly close to Yonaguni. PLA movements there are not rare, but uncommon, and Beijing's defense operations in the island's ADIZ generally has been minimal in recent weeks.

Late on Saturday, the ministry said China had been carrying out another “joint combat patrol” to “test our defensive capabilities”. It added the island had dispatched military assets to track the developments. Taiwan reports such Chinese patrols a couple of times a month as part of what Taipei says is an ongoing military pressure campaign.

Diplomatic Pressure

Japan has been experiencing increased strain from Beijing 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 “suitable actions”, though it did not elaborate.

Three Chinese airlines announced this weekend that flights to Tokyo 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.

Although not an outright prohibition, a dramatic reduction in the population of learners from China could have a detrimental effect on Japanese universities. A record 336,708 foreign nationals 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.

Media Response

Earlier this weekend, a official press commentary charged the Japanese official with performing 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 rapidly escalate to a major confrontation with severe repercussions.”

Policy Standpoints

The government of Taiwan says the island's residents alone determine their destiny. Japanese leaders have previously avoided publicly mentioning Taiwan when addressing potential conflicts, maintaining a “strategic ambiguity” also preferred by Japan's primary defense partner, 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 increasing its political operations and its rhetoric towards Taiwan.
