Beijing has mandated that Chinese mining firms operating abroad provide detailed reports on their reserves of critical minerals.
The Ministry of Commerce added more than 41 types of minerals to the reporting list, including rare earths and antimony.
This shift comes amidst increasing competition with the United States, particularly with Donald Trump taking office.
China's significant mineral deposits are essential for industries like electronics and electric vehicles, despite heavy reliance on imports for some key metals.
Experts suggest China’s control over critical minerals could serve as leverage in negotiations with the U.S. regarding trade and tariffs.
