A US Navy flight officer convicted last year of lying about his purchase of two pistols for a Chinese national was sentenced on Wednesday to four years in prison. Fan Yang, a 37-year-old lieutenant in the US Navy trained in anti-submarine warfare, was found guilty by a federal court jury in Florida of buying the guns for the head of a Chinese defence contracting firm who employed his wife. “(Lieutenant) Fan Yang swore an oath to protect this country, but instead he posed a significant risk to US national security when he failed to report his contact with the head of a Chinese defence contracting firm,” Sherri Onks, FBI special agent in charge of the agency’s Jacksonville field office, said in a written statement.

Prosecutors say the Chinese national, Ge Songtao, hired Yang’s wife for his company, Shanghai Breeze Technology Co. Ltd, in 2016 and ultimately paid her more than US$300,000. In 2017 and 2018 Yang bought two firearms for Ge, a Sig Sauer 9mm pistol and a Glock 9mm pistol, falsely representing that the guns were for himself, according to prosecutors.

He was convicted in November of conspiring to violate US firearms laws and making false statements as part of his security clearance.
