Neodymium is one of 17 metals crucial to green technology. There’s only one snag – China produces 97% of the world’s supply. And they’re not selling.

Britain and other Western countries risk running out of supplies of certain highly sought-after rare metals that are vital to a host of green technologies, amid growing evidence that China, which has a monopoly on global production, is set to choke off exports of valuable compounds....

China, whose mines account for 97 per cent of global supplies, is trying to ensure that all raw REE materials are processed within its borders. During the past seven years it has reduced by 40 per cent the amount of rare earths available for export.

Industry sources have told The Independent that China could halt shipments of at least two metals as early as next year, and that by 2012 it is likely to be producing only enough REE ore to satisfy its own booming domestic demand, creating a potential crisis as Western countries rush to find alternative supplies, and companies open new mines in locations from South Africa to Greenland to satisfy international demand.

Amid claims that Beijing is using its rare earths monopoly as a tool of foreign policy, the British Department of Business, Industry and Skills said it was "monitoring" the supply of REEs to ensure China was observing international trade rules.

This would be a good time to invest in Molycorp in Mountain Pass, CA. They were at one time producing 40% of world use of rare earth. And it seems they mine the same minerals China is banning....
