The Download: China's semiconductor fightback, and New York's controversial AI law

China has been on the receiving end of semiconductor export restrictions for years. On July 3, the Chinese Ministry of Commerce announced that the export of gallium and germanium, two elements used in producing chips, solar panels, and fiber optics, will soon be heavily restricted. Exports of the materials will need to be approved by the government, and Western companies that rely on them could have a hard time securing a supply. Even though the news immediately sent the price of gallium and germanium up, the curbs are not likely to hit the US as hard as American export restrictions have hit China. Zeyi Yang, our China reporter, explains why.
