US' attacks on Chinese tech development a double-edged sword that harms itself

In his remarks at the 78th session of the United Nations General Assembly on Tuesday, US President Joe Biden once again stressed that the United States seeks to responsibly manage the competition with China so "it does not tip into conflict" and claimed that it pursues "de-risking, not decoupling with China".
Yet the same day, US Secretary of Commerce Gina Raimondo told a US House of Representatives hearing that she was "upset" by news of the launch of Huawei's Mate 60 Pro during her visit to China last month. "The only good news, if there is any, is we don't have any evidence that they can manufacture 7-nanometer (chips) at scale," she said. Which clearly exposes the zero-sum mentality that prevails in Washington.
When China adopted its reform and opening-up policy in 1978, the US was a main source of knowledge and experiences that it learned from. Likewise, it was by absorbing talent and ideas from all over the world that the US turned itself into the leading global powerhouse for the development of technologies after World War II. Now, half a century later, the US is striving to prevent China doing the same. That means that the US will continue sanctioning China by targeting its high-tech sector.
