China has come under a lot of fire for its proectionist trade policies from mulitnational corporations like Siemens,GE,Google as well as its major trading partners.One of the bones of contention is its export restrictions on crucial minerals like zinc,lead,cadmium, gold, indium, iron ore, lime, lead, manganese, mercury, molybdenum, phosphate, salt, tin, tungsten, vanadium and zinc.China is surprisingly the biggest producer of these minerals and has been hoarding these minerals.Note China is the biggest importer of minerals like copper,coal,iron ore etc. so its hoarding is surprising.This action by China came under the scanner when it restricted the export of rare earth minerals over a small dispute with Japan.This resulted in alarm bells ringing in Europe,USA and Japan.These countries scurried for alternative sources of these crucial REE in other places as China controlled more than 95% of the world's supply.
