[Photo/Agencies] BEIJING -- A Chinese spokesperson on Thursday rebuked some Western politicians for questioning the impartiality of the recent coronavirus origin-tracing study by a World Health Organization (WHO) mission in China, saying being impartial does not mean "being at the behest of the West." Being impartial should not mean the presumption of guilt aimed at China, Foreign Ministry spokesperson Hua Chunying said at a press briefing.
