A former CIA officer, Alexander Yuk Ching Ma, has been sentenced to 10 years in prison followed by five years of supervised release for "conspiracy to commit espionage" on behalf of the Chinese government.

The 71 year old, a naturalised U.S. citizen originally born in Hong Kong, was arrested in August 2020 after "admitting to an undercover FBI agent that he sold US secrets to China," according to the Justice Department.
