Top US lawmakers are urging the Biden administration to put Chinese semiconductor company Yangtze Memory Technologies Co on a blacklist for allegedly violating export controls by supplying Huawei.

Democratic Senate Majority Leader Chuck Schumer told the Financial Times that he was concerned about a report, obtained by the FT, that showed YMTC has provided NAND memory chips for the Mate Xs 2, the new flagship foldable phone from Huawei, the Chinese telecoms equipment giant.
