China is a most important source of precursor chemical compounds vital for the manufacturing of cocaine, heroin, MDMA and crystal methamphetamine, which are used with the aid of many Southeast Asian and Pacific Rim nations. China produces over 100,000 metric tons of acetic anhydride each year, and imports an additional 20,000 metric heaps from the United States and Singapore. Reports point out that acetic anhydride is diverted from China to morphine and heroin refineries in the Golden Triangle.[citation needed] China is also a main exporter of bulk ephedrine and has been a supply united states for a good deal of the ephedrine and pseudoephedrine imported into Mexico; these precursor chemicals are due to this fact used to manufacture methamphetamine destined for the United States. China is developing a widespread MDMA production, trafficking, and consumption problem. Although China has taken actions thru rules and rules of production and exportation of precursor chemicals, considerable action is required to control the illicit diversion and smuggling of precursor chemicals.
