Business China says the price for both neodymium and dysprosium "continue to rise steeply due to mining restrictions and the cutting of export quotas for rare-earth minerals by China." China exports over 90 percent of the world's rare-earth metals and houses more than one third of the world's reserves, according to Business China. The market is controlled by the Chinese government, which in recent years has limited export quotas.

The price of neodymium has risen to RMB 1.4 million per ton from RMB 100,000 per ton since the end of 2008, when China issued a series of tightening measures for the country’s rare-earth industry, according to a survey by the 21st Century Business Herald.
