China Sends Maritime Patrol Vessels to Senkaku Islands During Dispute with Japan

Beijing has deployed its coast guard through the maritime area of the Senkaku islands and unmanned aerial vehicles past remote Japanese territory as Beijing escalates tensions following the Japanese prime minister’s remarks regarding Taiwan.

Rights Enforcement Activities

This past Sunday, the Chinese coast guard announced that its ships conducted a “rights enforcement patrol” through the territorial seas of the Diaoyu islands, which are administered by Tokyo but also claimed by Beijing.

“China coast guard vessel 1307 formation conducted patrols within the territorial waters of the Diaoyu islands. This was a legitimate rights enforcement activity undertaken by the China coast guard to uphold its rights and interests,” officials declared.

Diplomatic Spat

China and Japan have repeatedly faced off around the disputed territory but the recent developments come amid an escalating political dispute after the Japan's leader, the Japanese official, told parliament that if Beijing assaults the self-governing island of Taiwan it might provoke a military response from Tokyo.

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

Island's Stance

Beijing asserts the island as its sovereign land and intends to annex it under what it terms “unification”. It has left open the military option. Taiwan’s government and people overwhelmingly reject the idea of Beijing's control – choosing to preserve the current situation without formally announcing independence, but pledging to protect their sovereignty if necessary.

An military assault by Beijing would threaten to spiral into a international confrontation, possibly drawing in the United States and other allies including Japan, which has land just 110km (68 miles) from Taiwan.

Military Activity

In Taiwan, the military authorities reported this weekend that it had observed 30 Chinese military aircraft, multiple naval vessels and one government vessel, which was probably the maritime patrol, operating around the island over the previous day.

Official charts released showed up to multiple UAVs flying between the island and the Japan's territory off its north-east coast, seeming to travel unusually near to the nearby Japanese island. Chinese military transits there are not rare, but infrequent, and Beijing's defense operations in Taiwan’s air defence identification zone generally has been low in recent weeks.

Earlier this weekend, the ministry said Beijing had been conducting another “combined military exercise” to “test our defensive capabilities”. It noted Taiwan had dispatched military assets to monitor the situation. The island documents these operations a couple of times a month as part of what the Taiwanese government says is an continuous strategic pressure.

Political Strain

Tokyo has been facing mounting pressure from Beijing since Takaichi made her comments, with Beijing's diplomatic representative in the Japanese city prompting a formal protest from Tokyo by stating that “those who interfere will face consequences”.

China then summoned the Japanese ambassador for the first occasion since 2023, and Beijing's military authorities declared that any Tokyo's involvement would be doomed to fail.

Travel and Education Advisory

On Friday, Beijing cautioned its citizens against travelling to Japan, prompting Tokyo to urge Beijing to take “appropriate measures”, though it did not elaborate.

Three Chinese airlines said on Saturday that tickets to Japan could be refunded or changed for free.

Adding to the tensions, Beijing's administration on the weekend urged its citizens to “carefully reconsider” studying in Japan, citing what it described 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 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 largest demographic.

Media Response

Late on Saturday, a official press commentary accused Takaichi of staging a political stunt that was “both reckless and fundamentally flawed”.

“A conflict between Japan and China would not be a small-scale encounter; it would probably involve other nations, including the US, and could rapidly escalate to a large-scale conflict with unimaginable consequences.”

Policy Standpoints

The administration in Taipei says the island's residents alone determine their destiny. Japanese leaders have traditionally refrained from publicly mentioning Taiwan when discussing such scenarios, maintaining a “deliberate vagueness” also favoured by Tokyo’s main security ally, the United States.

Nevertheless, Beijing's governing party says the incorporation of the island with the mainland China is “inevitable”, and portrays dissent as provocative. As it advances toward potential armed takeover, China has also been escalating its non-military activity and its rhetoric towards the island.
