The World Trade Organization (WTO) has ruled that China broke international rules by restricting the exports of certain metals.
The case, which dates back to 2009, was brought after China imposed quotas, saying it had to conserve resources of magnesium and other exports.
The US said this left non-Chinese manufacturers with shortages of the necessary metals.
The US was supported in its case by the EU and Mexico.
