A high-ranking Chinese spy chief is rumoured to have defected to the United States and given Washington evidence on the Wuhan lab which prompted Joe Biden's about-face on the coronavirus leak theory.
Dong Jingwei is believed to have fled to the US with his daughter Dong Yang on February 10, according to Spy Talk.
He made a name in China's secret service, known as Guoanbu, and was head of counter-intelligence, or spy-catching, after being promoted to the post of vice minister in April 2018.
