CANBERRA, Australia -- Australia’s defense minister said on Wednesday he had told the nation’s military to review secrecy safeguards in response to concerns that Beijing was recruiting pilots to train the Chinese People’s Liberation Army.Defense Minister Richard Marles ordered the review after asking the Defense Department last month to investigate reports that China had approached former Australian military personnel to become trainers.“In the information that has now been provided to me by Defense, there are enough concerns in my mind that I have asked Defense to engage in a detailed examination about the policies and procedures that apply to our former Defense personnel, and particularly those who come into possession of our nation’s secrets,” Marles told reporters.He said a joint police-intelligence service task force was investigating “a number of cases” among former service personnel.“For example, it’s pretty hard to charge anyone with treason outside wartime,” James told Australian Broadcasting Corp.James said there were no circumstances in which former Australian military personnel should be working with the Chinese."
