China said it sent warplanes into its newly declared maritime air defense zone Thursday, days after the U.S., South Korea and Japan all sent flights through the airspace in defiance of rules Beijing says it has imposed in the East China Sea.
China's air force sent several fighter jets and an early warning aircraft on normal air patrols in the zone, the Xinhua agency reported, citing air force spokesman Shen Jinke.
The report did not specify exactly when the flights were sent or whether they had encountered foreign aircraft. The United States, Japan and South Korea have said they have sent flights through the zone without encountering any Chinese response since Beijing announced the creation of the zone last week.
Shen described Thursday's flights as "a defensive measure and in line with international common practices." He said China's air force would remain on high alert and will take measures to protect the country's airspace.
While China's surprise announcement last week to create the zone initially raised some tensions in the region, analysts say Beijing's motive is not to trigger an aerial confrontation but is a more long-term strategy to solidify claims to disputed territory by simply marking the area as its own.
China's lack of efforts to stop the foreign flights - including two U.S. B-52s that flew through the zone on Tuesday - has been an embarrassment for Beijing. Even some Chinese state media outlets suggested Thursday that Beijing may have mishandled the episodes.
"Beijing needs to reform its information release mechanism to win the psychological battles waged by Washington and Tokyo," the Global Times, a nationalist tabloid published by the Communist Party's flagship People's Daily, said in an editorial.
Without prior notice, Beijing began demanding Saturday that passing aircraft identify themselves and accept Chinese instructions or face consequences in an East China Sea zone that overlaps a similar air defense identification zone overseen by Japan since 1969 and initially part of one set up by the U.S. military.
But when tested just days later by U.S. B-52 flights - with Washington saying it made no effort to comply with China's rules, and would not do so in the future - Beijing merely noted, belatedly, that it had seen the flights and taken no further action.
South Korea's military said Thursday its planes flew through the zone this week without informing China and with no apparent interference. Japan also said its planes have been continuing to fly through it after the Chinese announcement, while the Philippines, locked in an increasingly bitter dispute with Beijing over South China Sea islands, said it also was rejecting China's declaration.
Analysts question China's technical ability to enforce the zone due to a shortage of early warning radar aircraft and in-flight refueling capability. However, many believe that China has a long-term plan to win recognition for the zone with a gradual ratcheting-up of warnings and possibly also eventual enforcement action.
"With regard to activity within the zone, nothing will happen - for a while," said June Teufel Dreyer, a China expert at the University of Miami. "Then the zone will become gradually enforced more strictly. The Japanese will continue to protest, but not much more, to challenge it."
That may wear down Japan and effectively change the status quo, she said.
The zone is seen primarily as China's latest bid to bolster its claim over a string of uninhabited Japanese-controlled islands in the East China Sea - known as Senkaku in Japan and Diaoyu in China. Beijing has been ratcheting up its sovereignty claims since Tokyo's privatization of the islands last year.
But the most immediate spark for the zone likely was Japan's threat last month to shoot down drones that China says it will send to the islands for mapping expeditions, said Dennis Blasko, an Asia analyst at think tank CNA's China Security Affairs Group and a former Army attache in Beijing.
The zone comes an awkward time. Although Beijing's ties with Tokyo are at rock bottom, it was building good will and mutual trust with Washington following a pair of successful meetings between President Barack Obama and Chinese President Xi Jinping. However, the zone feud now threatens to overshadow both the visit by Vice President Joe Biden to Beijing next week and one by Australian Foreign Minister Julie Bishop expected before the end of the year.
China's defense and foreign ministries offered no additional clarification Thursday as to why Beijing failed to respond to the U.S. Air Force flights. Alliance partners the U.S. and Japan together have hundreds of military aircraft in the immediate vicinity.
China on Saturday issued a list of requirements for all foreign aircraft passing through the area, regardless of whether they were headed into Chinese airspace, and said its armed forces would adopt "defensive emergency measures" against aircraft that don't comply.
Beijing said the notifications are needed to help maintain air safety in the zone. However, the fact that China said it had identified and monitored the two U.S. bombers during their Tuesday flight seems to discredit that justification for the zone, said Rory Medcalf, director of the international security program at Australia's Lowy Institute
"This suggests the zone is principally a political move," Medcalf said. "It signals a kind of creeping extension of authority."
Along with concerns about confrontations or accidents involving Chinese fighters and foreign aircraft, the zone's establishment fuels fears of further aggressive moves to assert China's territorial claims - especially in the hotly disputed South China Sea, which Beijing says belongs entirely to it.
Defense Ministry spokesman Yang Yujun confirmed those concerns on Saturday by saying China would establish additional air defense identification zones "at an appropriate time."
For now, however, China's regional strategy is focused mostly on Japan and the island dispute, according to government-backed Chinese scholars.
China will continue piling the pressure on Tokyo until it reverses the decision to nationalize the islands, concedes they are in dispute, and opens up negotiations with Beijing, said Shen Dingli, a regional security expert and director of the Center for American Studies at Shanghai's Fudan University.
"China has no choice but to take counter measures," Shen said. "If Japan continues to reject admitting the disputes, it's most likely that China will take further measures."
