The Trump administration on Tuesday announced a ban on new foreign-made humanoid robot imports to the US over "unacceptable risks" to America's national security. The move applies to advanced robots - including humanoid and four-legged machines. The Chinese embassy in Washington said Beijing has long opposed the US' "politicising" of trade issues and sanctions based on "groundless pretexts". It called on the US to "abandon its hegemonic mindset, and stop smearing Chinese companies and threatening them with sanctions". The BBC has contacted major Chinese robot manufacturers Unitree, UBTech and AgiBot for comment.
