Chinese companies are buying up U.S. chipmaking equipment to make advanced semiconductors, despite a raft of new export curbs aimed at thwarting advances in the country's semiconductor industry, a congressional report said on Tuesday. The 741 page annual report, released by the House of Representative's bipartisan select committee on China, takes aim at the Biden administration's Oct. 2022 export curbs, which seek to bar Chinese chipmakers from getting U.S. chipmaking tools if they would be used to manufacture advanced chips at the 14 nanometer node or below. The finding comes as the United States scrambles to figure out how Chinese telecoms giant Huawei was able to produce an advanced 7 nanometer chip to power its Mate 60 Pro smartphone at China's top chipmaker SMIC, despite the export curbs announced last year.
