Singapore | China is tightening its grip over global critical mineral supplies by placing export controls on antimony, a metal used widely in ammunition and other military applications that has surged in price this year.
The country will apply the restrictions to antimony and antimony-related materials from September 15 to safeguard national security, a statement from the Ministry of Commerce said. That adds to earlier controls on other critical minerals including gallium and germanium, which have set off alarm bells in Washington.
