The Trump administration has banned new Chinese-made humanoid and four-legged robots from entering the US, citing what officials described as unacceptable national security risks. Advanced robotic devices include humanoid robots and four-legged machines. The measures are expected to have a major impact on Chinese robotics companies, which have rapidly expanded their humanoid robot businesses for use in factories, homes and other settings. The BBC contacted Chinese robot manufacturers Unitree, UBTech and AgiBot for comment. US Treasury Secretary Scott Bessent has also warned that Chinese AI companies could face sanctions over allegations of stealing American intellectual property.
