Dramatic fall in China rare earths exports
China's rare earths exports in April were 53% down on a year earlier and 12.6% from the March figure, yet export value per tonne rose ten-fold, customs data showed on Monday.
China, which controls about 97% of rare earth output, has angered customers in Japan, the United States and Europe by clamping down on production and sale of the 17 rare earth elements, citing a need to clean up highly polluting production processes and to stop illegal exports.
