Nine months after the original brouhaha over China’s plans to decrease dramatically its exports of rare earths, the international community has called foul again on a closely related issue: China’s export curbs on other raw materials, such as magnesium and silicon. On July 5th, the World Trade Organization (WTO) ruled that China had violated WTO rules when it curbed its exports of these and other raw materials. (Thus far, the Chinese response to the first ruling has been muted, but all indications are that Beijing will appeal the ruling.)
