China hit back at US over allegations linking an alleged Chinese spy to Nvidia CEO Jensen Huang, accusing Washington of fabricating a spying narrative to justify imposing a technological blockade.“China urges the US to stop fabricating so-called spy narratives and using them as a pretext for imposing a technological blockade,” foreign ministry spokesperson Mao Ning said at a regular briefing on Thursday, as quoted by Reuters.She added that China’s scientific and technological progress was driven by independent innovation and open cooperation. Beijing was also willing to work with Washington to implement the consensus reached by the two countries’ leaders, she added.The latest remarks come amid growing scrutiny of Nvidia and its chief executive Jensen Huang after reports linked him to Alice Huang, a Chinese businesswoman suspected by US intelligence officials of working for Beijing. The allegations have not been independently verified by Reuters.Meanwhile, Nvidia’s board has launched an independent investigation into whether Huang was targeted by a foreign intelligence operation. The CEO admitted in a message to employees that he had been unfaithful to his wife, but did not name the woman. He has said he would cooperate with the probe and reaffirmed his commitment to US national security. Nvidia has said it has no reason to believe that national security information or company trade secrets were compromised.Beijing had rejected the espionage allegations earlier this week as well. On Monday, foreign ministry spokesperson Guo Jiakun called the claims “unsubstantiated” and “nothing but smears against China”.
