China Sends Coast Guard Ships to Diaoyu Islands Amid Dispute with Tokyo

Beijing has sent its coast guard through the maritime area of the Diaoyu islands and unmanned aerial vehicles near outlying Japan's territory as Beijing ramps up strains over the Japan's leader's comments regarding Taiwan.

Rights Enforcement Activities

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

“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 China coast guard to protect its sovereign claims,” the statement said.

Bilateral Tensions

Beijing and Tokyo have consistently clashed around the islands but the latest activity occur during an intensifying diplomatic spat after the Japan's leader, the Japanese official, told parliament that if Beijing assaults the self-governing island of Taiwan it could trigger a armed reaction from Japan.

That provoked a furious reaction from Beijing, which has signalled it expects a retraction from the Japanese official.

Taiwan's Position

China claims the island as its sovereign land and plans to incorporate it under what it terms “reunification”. It has left open the use of force. The island's administration and people categorically refuse the idea of Beijing's control – preferring to maintain the status quo without formally announcing independence, but pledging to protect their sovereignty if necessary.

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

Defense Operations

In Taiwan, the defence ministry reported this weekend that it had observed 30 Chinese military aircraft, multiple naval vessels and one “official” ship, which was likely the coast guard, active near the territory over the previous day.

Maps provided by the ministry showed up to three drones operating near the island and the Japanese islands off its north-east coast, appearing to go particularly close to the nearby Japanese island. Chinese military transits 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 defense officials said Beijing had been conducting another “joint combat patrol” to “harass the airspace and sea around us”. It noted Taiwan had sent its own aircraft and ships to track the developments. The island reports such Chinese patrols a couple of times a month as part of what the Taiwanese government says is an ongoing military pressure campaign.

Political Strain

Tokyo has been experiencing increased strain from Beijing since Takaichi made her comments, with Beijing's diplomatic representative in the Japanese city triggering an official complaint from Tokyo by commenting that “those who interfere will face consequences”.

Beijing then summoned the Japanese ambassador for the first occasion since 2023, and China’s defence ministry stated that any Tokyo's involvement would be certain to collapse.

Travel and Education Advisory

On Friday, Beijing advised its people to avoid visiting 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, China’s government on Sunday urged its citizens to “carefully reconsider” studying in Japan, citing what it characterized as an volatile safety situation.

While the advice does not amount to a ban, a dramatic reduction in the number of Chinese students could have a detrimental effect on Japanese universities. A historic high of over 336,000 international students were studying in Japan last year, according to official data. They included more than 123,000 Chinese students – by far the largest demographic.

Media Response

Earlier this weekend, a Chinese state media editorial charged the Japanese official with performing a political stunt that was “both reckless and fundamentally flawed”.

“A clash between Tokyo and Beijing would not be a limited skirmish; it would probably involve other nations, including the United States, and could quickly spiral into a major confrontation with severe repercussions.”

Strategic Positions

The government of Taiwan says the island's residents alone determine their destiny. Japanese leaders have traditionally refrained from publicly mentioning Taiwan when addressing potential conflicts, maintaining a “deliberate vagueness” also preferred by Japan's primary defense partner, the US.

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 moves towards being capable of military annexation, China has also been escalating its non-military activity and its statements towards the island.
