U.S. officials said chips manufactured by China's Jungshin Co. for Huawei may violate U.S. law.
Voice of America reported on March 22 that a senior US official said that China's largest chipmaker, Zhongxin International Corporation (SMIC) made advanced seven-nanometer chips for Chinese telecommunications giant Huawei that may violate US law. The news caused Zhongshin's share price to drop 5.5% on the Hong Kong stock market on March 22.
Alan Estevez, the US Commerce Department's industrial and security adviser, said at a congressional hearing on Thursday whether Zhongxin International's 7-nanometer chip manufacturing for Huawei violated US export controls: "It's a possibility, we'll have to evaluate it."
The hearing also raised questions about whether Zhongxin illegally used U.S. equipment in the production of related chips.
In recent years, the United States has tightened controls on the sale of key technologies in the field of artificial intelligence to China, and Huawei has been at the center of a technology battle between the United States and China for years. The US government has warned that Huawei's telecommunications equipment may be used for state espionage, but Huawei has denied this. In August last year, Huawei released the Mate 60 Pro, a G5 chip-equipped smartphone manufactured by Jungshin Co., Ltd., announcing that it would tolerate US sanctions.
The launch of the drone has fueled debate about the effectiveness of US efforts to deter China. The Biden administration has also been asked to investigate the technology used by China and learn the details of the chip.
