BEIJING: China sent fighter jets and an early warning aircraft into its newly declared air defense zone, state media said Friday, as Japan and South Korea stated they had defied the zone with military overflights.
The Chinese planes had conducted normal air patrols on Thursday as “a defensive measure and in line with international common practices,” said Shen Jinke, spokesman for the People’s Liberation Army (PLA) Air Force, according to state news agency Xinhua.
Shen said China’s air force would remain on high alert and take measures to protect the security of the country’s airspace, Xinhua reported.
Japan and South Korea said Thursday they had defied the air defense
identification zone (ADIZ) declared by Beijing last weekend, showing a united front after US B-52 bombers did the same.
Chinese authorities are coming under domestic pressure to toughen their response to incursions into the zone that includes disputed islands claimed by China, which knows them as the Diaoyus, but controlled by Japan, which calls them the Senkakus.
The move triggered US and Japanese accusations of provocation as global concerns grew.
China’s ADIZ requires aircraft to provide their flight plan, declare their nationality and maintain two-way radio communication—or face “defensive emergency measures”.
But Tokyo said its coastguard and air force had flown unopposed in the zone without complying with Beijing’s rules.
“We have been operating normal warning and patrol activities in the East China Sea including that area,” said Chief Cabinet Secretary Yoshihide Suga. “We have no intention of changing this.”
South Korea’s military said it encountered no resistance when one of its planes entered the area —which also overlaps Seoul’s ADIZ—unannounced on Tuesday.
A day earlier two giant US Stratofortress bombers flew into the zone, an unmistakable message from Washington before a pre-planned visit to the region by Vice President Joe Biden.
China’s defense ministry issued a statement 11 hours after the US announcement saying its military “monitored the entire process” of the B-52 flights, without expressing regret or anger or threatening direct action.
The Global Times, which is close to China’s ruling Communist Party and often takes a nationalist tone, criticized the reaction as “too slow” in an editorial Thursday.
“We failed in offering a timely and ideal response,” it said, adding that Chinese officials needed to react to “psychological battles” by the US.
Asked about the South Korean flight, China’s foreign ministry spokesman Qin Gang said: “China identifies any aircraft within the ADIZ and must have noted the relevant situation you have mentioned.”
He reiterated criticism of US and Japanese responses to the zone, urging both countries to “immediately correct their mistakes and stop their irresponsible accusations against China”.
The Communist Party seeks to drum up popular support by tapping into deep-seated resentment of Japan for its brutal invasion of China in the 1930s.
China’s relations with South Korea have recently improved but the zone covers a disputed South Korean-controlled rock that has long been a source of tensions between them.
South Korea’s Vice Defense Minister Baek Seung-Joo expressed “strong regret” at China’s ADIZ announcement, which he said was “heightening military tension in the region.”
Australia on Thursday refused to back down from criticism of the air zone after summoning China’s ambassador earlier this week and prompting an angry response from Beijing.
The Philippines voiced concern that China may extend control of air space over disputed areas of the South China Sea, where the two nations have a separate territorial dispute.
China for its part has accused the US and Japan—which both have ADIZs—of double standards, saying the real provocateur is Tokyo.
Defense ministry spokesman Yang Yujun said in a statement Thursday that Japan established its ADIZ in 1969, so Tokyo had “no right to make irresponsible remarks” about China’s.
“If there are to be demands for a withdrawal, then we invite the Japanese side to first withdraw its air defence identification zone, and China may reconsider after 44 years,” he said.
