Foreign Ministry spokesman Zhao Lijian said on Wednesday that the United States cares nothing about facts or truth, but only about how to exhaust and smear China by launching an investigation over the so-called "lab leak theory" that presumes China is guilty.

Zhao made the remark after media reports cited informed sources as saying that the US intelligence agency still intends to release a report that makes up misleading conclusions over the COVID-19 origins, despite the lack of concrete proof, and that high-level US officials believe the real purpose is to hype up the origin investigation with the aim of exhausting China's diplomatic resources and increasing US leverage regarding China.
