A Chinese national has been sentenced to 30 months in a U.S. prison for smuggling or trying to smuggle high-tech U.S. military hardware to China.

Kan Chen of Ningbo, in China's Zhejiang province, was convicted of illegally exporting or trying to export more than 180 items worth more than $275,000, including night vision and thermal imaging rifle scopes.

"The United States will simply never know the true harm of Chen's conduct because the end users of the rifle scopes and other technology are unknown," U.S. Attorney Charles Oberly said.

Chen was arrested in Saipan in June 2015 and pleaded guilty in March. He was also sentenced to three years of supervised release.
