The US has asked Australia to extradite a former marine accused of breaking American arms control laws by training Chinese fighter pilots.
Daniel Duggan, a former US citizen, has been in custody since his arrest in Australia in October.
Mr Duggan says he hasn't broken any laws and his lawyer argues the charges are politically motivated.
Nations including Australia and the UK are warning air force personnel against taking similar lucrative contracts. เช็กชี่บาคาร่า66
Mr Duggan is facing four charges in the US over "military training" they say he provided to Chinese pilots at a "test flying academy" in South Africa more than a decade ago.
Reuters earlier this week reported the contents of Mr Duggan's indictment, which claimed he did not seek authorisation from the US government to provide military training to China, despite the US State Department informing him by email in 2008 that he had to do so to train a foreign air force.
