Beijing has deployed its coast guard through the waters of the Diaoyu islands and military drones past outlying Japanese territory as China ramps up tensions over the Japanese prime minister’s remarks regarding the island of Taiwan.
On Sunday, the China's maritime patrol stated that its ships carried out a “rights enforcement patrol” through the waters of the Diaoyu islands, which are under the control of Japan but also claimed by China.
“Chinese maritime patrol unit 1307 conducted patrols within the maritime jurisdiction of the Diaoyu islands. This was a lawful patrol operation conducted by the Chinese maritime authorities to uphold its rights and interests,” officials declared.
China and Japan have repeatedly faced off around the islands but the latest activity come amid an intensifying diplomatic spat after the Japanese prime minister, Sanae Takaichi, told parliament that if China attack democratically ruled Taiwan it might provoke a military response from Tokyo.
That sparked an angry response from Beijing, which has indicated it demands a withdrawal from Takaichi.
China claims Taiwan as its own territory and plans to incorporate it under what it describes as “reunification”. It has left open the military option. The island's administration and people categorically refuse the prospect of Chinese rule – preferring to maintain the status quo without explicitly declaring themselves independent, but vowing to defend themselves if required.
An attack or invasion by Beijing would threaten to spiral into a regional or global conflict, possibly drawing in the US and other allies including Tokyo, which has land just 110km (68 miles) from the island.
On the island, the military authorities reported this weekend that it had detected 30 Chinese military aircraft, seven navy ships and one government vessel, which was likely the coast guard, operating around the island over the past 24 hours.
Maps provided by the ministry showed up to three drones flying between Taiwan and the Japanese islands off its north-east coast, appearing to go particularly close 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 recent weeks.
Earlier this weekend, the ministry said China had been carrying out another “joint combat patrol” to “harass the airspace and sea around us”. It added the island had dispatched military assets to monitor the situation. Taiwan documents these operations a few times monthly as part of what the Taiwanese government says is an continuous strategic pressure.
Japan has been facing mounting pressure from China since Takaichi made her remarks, with China’s consul general in the Japanese city prompting a formal protest from Tokyo by stating that “the dirty head that sticks itself out must be cut off”.
Beijing then called in Japan's diplomat for the first time in more than two years, and China’s defence ministry stated that any Tokyo's involvement would be doomed to fail.
On Friday, China advised its people to avoid visiting Japan, prompting Tokyo to urge Beijing to take “suitable actions”, though it did not elaborate.
Multiple carriers from China said on Saturday that flights to Tokyo could be refunded or changed for free.
Adding to the tensions, China’s government 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 number of Chinese students could have a negative impact on academic institutions in Japan. 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 single biggest group.
Late on Saturday, a Chinese state media editorial 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 likely draw in other powers, including the US, and could quickly spiral into a major confrontation with unimaginable consequences.”
The administration in Taipei says only its people can decide its future. Officials in Tokyo have traditionally refrained from discussing the island openly when addressing potential conflicts, maintaining a “strategic ambiguity” also favoured by Tokyo’s main security ally, the US.
Nevertheless, China’s ruling Communist party says the unification of Taiwan 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 Taiwan.
