Australia-China row: 'I'm Australian - why do I need to prove my loyalty?'
By Frances Mao
Earlier this year, a junior adviser for the Australian government, Andrew Chen*, visited the nation's Department of Defence for a meeting.
As he and a colleague stepped into the building in Canberra, they pulled out their government IDs. Mr Chen was stopped by a guard, who took him aside.
"They asked to take a photo of me - like a portrait - there in the lobby," he said.
"And it was just me. The Caucasian colleague who was with me - he wasn't asked to do that," added Mr Chen, who is Chinese-Australian.
