China Export Prohibition of Rare Earth Production Technology & Application Know-How

China has been prohibiting and restricting export of China's rare earth production and application know-how since 2001.

The 2008 publication of the revision of the 2001 decree contains two lists, one prohibited technologies and one controlled technologies (subject to permits). There is another list which refers to dual-use products as per international agreements.

Those parts of the that concern rare earths read as follows:
