DeBar made the remarks in an interview with Press TV on Friday while commenting on escalating tensions between the US and China over number of issues.
China has lambasted as "dirty play” the US clampdown on Chinese telecom giant Huawei, a day after Washington announced fresh sanctions on the company and other firms of the Asian country.
Chinese Foreign Ministry spokeswoman Hua Chunying on Thursday retorted at a regular press conference that “what the US does has nothing to do with the word 'clean'… What it does is... dirty play.”
Her comments came just a day after the White House announced visa restrictions for Huawei employees and those working for other Chinese firms if they were involved in alleged human rights abuses.
China and the US are at odds over a growing number of issues, including the origin of the new coronavirus and Beijing’s policies in Hong Kong.
