China Dispatches Maritime Patrol Ships to Diaoyu Islands Amid Dispute with Japan

Beijing has deployed its maritime law enforcement into the waters of the Senkaku islands and unmanned aerial vehicles near remote Japanese territory as Beijing escalates tensions over the Japanese prime minister’s remarks regarding Taiwan.

Patrol Operations

This past Sunday, the China's maritime patrol announced that its ships carried out a “lawful patrol operation” through the territorial seas of the Diaoyu islands, which are under the control of Japan but also asserted as territory by Beijing.

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

Diplomatic Spat

Beijing and Tokyo have repeatedly faced off around the disputed territory but the recent developments come amid an intensifying diplomatic spat after the Japanese prime minister, Sanae Takaichi, addressed lawmakers that if Beijing assaults democratically ruled Taiwan it might provoke a military response from Tokyo.

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

Island's Stance

China claims Taiwan as its sovereign land and intends to annex it under what it terms “reunification”. It has left open the use of force. Taiwan’s government and people categorically refuse 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 China would threaten to spiral into a international confrontation, possibly drawing in the US and other partner nations including Tokyo, which has territory just 110km (68 miles) from Taiwan.

Military Activity

In Taiwan, the defence ministry reported this weekend that it had detected 30 Chinese military aircraft, multiple naval vessels and one government vessel, which was probably the coast guard, operating around the island over the past 24 hours.

Official charts released showed up to three drones flying between the island and the Japanese islands off its northeastern shoreline, appearing to go unusually near to the nearby Japanese island. Chinese military transits there are occasional, but uncommon, and Chinese military activity in Taiwan’s air defence identification zone generally has been minimal in the past month.

Late on Saturday, the ministry said Beijing had been carrying out another “combined military exercise” to “test our defensive capabilities”. It added the island had sent its own aircraft and ships to monitor the situation. Taiwan documents these operations a couple of times a month as part of what the Taiwanese government says is an continuous strategic pressure.

Political Strain

Japan has been facing mounting pressure from China since Takaichi made her comments, with China’s consul general in Osaka triggering an official complaint from Japan by commenting that “those who interfere will face consequences”.

Beijing then summoned the Japanese ambassador for the first time in more than two years, and China’s defence ministry declared that any Japanese intervention would be certain to collapse.

Travel and Education Advisory

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

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

In another escalation, Beijing's administration on Sunday advised students to rethink education plans 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 population of learners from China could have a detrimental effect on academic institutions in Japan. 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 single biggest group.

Official Commentary

Earlier this weekend, a Chinese state media editorial accused Takaichi of staging a diplomatic maneuver that was “not just dangerously provocative but fundamentally perverse”.

“A clash between Tokyo and Beijing would not be a limited skirmish; it would likely draw in other nations, including the US, and could rapidly escalate to a major confrontation with unimaginable consequences.”

Strategic Positions

The administration in Taipei says the island's residents alone determine their destiny. Japanese leaders have previously avoided publicly mentioning Taiwan when discussing such scenarios, maintaining a “deliberate vagueness” 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 “inevitable”, and portrays dissent as provocative. As it moves towards being capable of military annexation, China has also been increasing its political operations and its statements towards the island.
