The Chinese Embassy in the UK issued a statement: Strongly condemning the UK’s unreasonable accusations. The British side is hyping up the so-called "Chinese cyber attack" without any basis and even announcing sanctions.
This is outright political manipulation and malicious slander. Whether the British government is good or bad, the British people will come to a conclusion sooner or later, the statement said. The statement emphasized that we strongly urge the British side to immediately stop spreading false information about China, stop directing and performing anti-China farces.
