The information passed on related to Taiwan's new air defence system
A former Pentagon analyst who passed military secrets to a Chinese spy has been sentenced to almost five years in prison by a US court.
Gregg Bergersen pleaded guilty in March to disclosing defence information to a New Orleans businessman, Tai Shen Kuo.
Much of the information was about US military sales to Taiwan.
Mr Bergersen admitted accepting gifts from Mr Kuo, along with cash payments and money for gambling trips to Las Vegas.
A court in Virginia sentenced Mr Bergersen to 57 months imprisonment, and a further three years supervision upon release.
He had faced a maximum sentence of 10 years in prison.
Mr Bergersen had been unaware that Mr Kuo was passing the information on to the Chinese government.
Mr Kuo, who was arrested in February, will go on trial next month.
