THE United States has been hyping up the so-called "lab leak" conspiracy theory recently and is once again shifting the blame on the origins of Covid-19 to China. In fact, at the very beginning of the global outbreak of Covid-19, the administration of US former president Donald Trump had already made up wave after wave of conspiracy theories to smear China with the groundless presumption of guilt in an attempt to cover up their incompetence in coping with the pandemic.
With the worsening pandemic situation compounding the presidential election last year, the US was focused on dealing with its domestic problems. However, as the situation is getting better to some extent, the Biden administration is beginning to create a fuss again over tracing the origins of Covid-19 and overtly targeting China as the culprit.
