China’s chipmaking export curbs ‘just a start’, Beijing adviser warns before Yellen visit

BEIJING/SHANGHAI: China’s export controls on metals used in semiconductors are “just a start”, an influential Chinese trade policy adviser said on Wednesday, as Beijing ramps up a tech fight with Washington days before a visit from U.S. Treasury Secretary Janet Yellen.

Shares in some Chinese metals companies rallied for a second session as investors bet that higher prices for gallium and germanium, which Beijing’s export restrictions target, could boost revenues.
