Beijing Sends Maritime Patrol Ships to Diaoyu Islands During Dispute with Tokyo

Beijing has sent its coast guard into the maritime area of the Senkaku islands and military drones near remote Japan's territory as China escalates strains following the Japanese prime minister’s comments regarding Taiwan.

Patrol Operations

On Sunday, the Chinese coast guard announced that its ships carried out a “rights enforcement patrol” through the territorial seas of the Diaoyu islands, which are under the control of Tokyo but also asserted as territory by Beijing.

“China coast guard vessel 1307 formation conducted patrols within the territorial waters of the Senkaku islands. This was a lawful patrol operation conducted by the China coast guard to protect its sovereign claims,” officials declared.

Bilateral Tensions

Beijing and Tokyo have consistently clashed around the disputed territory but the latest activity occur during 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 military response from Japan.

That provoked a furious reaction from China, which has indicated it demands a retraction from the Japanese official.

Island's Stance

Beijing asserts the island as its own territory and intends to annex it under what it describes as “unification”. It has left open the military option. The island's administration and citizens categorically refuse the idea of Beijing's control – choosing to preserve the current situation without formally announcing independence, but vowing to defend themselves if necessary.

An attack or invasion by Beijing would threaten to spiral into a regional or global conflict, possibly drawing in the United States and other partner nations including Japan, which has territory just 110km (68 miles) from Taiwan.

Military Activity

In Taiwan, the defence ministry reported this weekend that it had observed 30 Chinese military aircraft, seven navy ships and one “official” ship, which was likely the coast guard, operating around the island over the past 24 hours.

Maps provided by the ministry showed up to multiple UAVs flying between the island and the Japanese islands off its north-east coast, seeming to travel particularly close to Yonaguni. Chinese military transits there are occasional, but uncommon, and Chinese military activity in Taiwan’s air defence identification zone generally has been minimal in recent weeks.

Late on Saturday, the ministry said Beijing had been carrying out another “combined military exercise” to “harass the airspace and sea around us”. It added the island had sent its own aircraft and ships to track the developments. Taiwan reports such Chinese patrols a couple of times a month as part of what the Taiwanese government says is an continuous strategic pressure.

Diplomatic Pressure

Tokyo has been experiencing increased strain from Beijing since Takaichi made her remarks, with Beijing's diplomatic representative in the Japanese city prompting a formal protest from Tokyo by stating 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 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, prompting Tokyo to urge Beijing to take “appropriate measures”, though it provided no details.

Three Chinese airlines said on Saturday 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 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 negative impact on Japanese universities. A historic high of over 336,000 international students were studying in Japan last year, according to official data. They featured over 123,000 learners from China – 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 “not just dangerously provocative but fundamentally perverse”.

“A conflict between Japan and China would not be a limited skirmish; it would probably involve other powers, including the United States, and could rapidly escalate to a major confrontation with unimaginable consequences.”

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 Tokyo’s main security ally, the US.

However, China’s ruling Communist party says the unification of Taiwan with the mainland China is “unavoidable”, and portrays dissent as provocative. As it moves towards being capable of military annexation, Beijing has also been increasing its political operations and its statements towards Taiwan.
