China tightens export rules for crucial rare earths

BBC:

China has tightened its rules on the export of rare earths – the elements that are crucial to the manufacture of many high-tech products.

New regulations announced by the country’s Ministry of Commerce formalise existing rules on processing technology and unauthorised overseas cooperation.

China is also likely to block exports to foreign arms manufacturers and some semiconductor firms.

Rare earth exports are a key sticking point in the months-long negotiations between Beijing and Washington over trade and tariffs. The announcement comes as China’s President Xi Jinping and his US counterpart Donald Trump are expected to meet later this month.
