SYDNEY, Dec 17 - Australia will not bow to Chinese pressure to halt surveillance flights over disputed islands in the East Vietnam Sea at the centre of rival claims between China and some of its neighbors, Defence Minister Marise Payne said on Thursday.
The Australian Defence Department said on Tuesday one of its aircraft had flown "a routine maritime patrol" over the East Vietnam Sea from Nov. 25 to Dec. 4, just as the U.S. Pacific Fleet Commander warned that a possible arms race could engulf the region.
China claims most of the East Vietnam Sea, through which more than $5 trillion of world trade ships every year, a fifth of it heading to and from U.S. ports.
Vietnam, Malaysia, Brunei, the Philippines and Taiwan also claim parts of the East Vietnam Sea.
China is building seven man-made islands on reefs in Vietnam’s Truong Sa (Spratly) Islands, including a 3,000-metre-long (10,000-foot) airstrip on one of the sites, according to satellite imagery.
Such activity has fanned regional tension. In October, a U.S. guided missile destroyer sailed close to one of China's man-made islands, drawing an angry rebuke from Beijing. U.S. defence officials say another U.S. patrol this year is unlikely.
Payne said Canberra would not be deterred by warnings from Beijing, which again responded angrily to the Australian patrol, and described the flights as a routine part of Australia's role in helping to maintain regional stability and security.
"We always navigate in a very constructive way in the region," she told reporters in Adelaide.
China's Foreign Ministry, asked about the Australian flights, said this week countries outside the region should not "deliberately complicate the issue".
Ministry spokesman Hong Lei said on Thursday he had nothing to add.
Chinese media has not been so restrained.
On Wednesday, influential tabloid the Global Times, published by the official People's Daily, implied there could be military retaliation if Australia persisted with the patrols.
"Australian military aircraft had better not regularly come to the [East Vietnam Sea] to add to the trouble, and especially not test China's patience by getting close to China's islands and reefs," it said in an editorial.
China and Australia are friends and should act that way, it said.
"It really ought not to happen that one day, due to a freak combination of factors, coincidentally an aircraft was downed and it just happened to be Australian."
