Since 1974, Myanmar has co-operated with the U.S. government in
the anti-narcotic operations and was highly commended for
her efforts by that government. The U. S. Government assisted Myanmar with $ 68 millions for a period of 14 years starting from 1974 to 1988 mainly in training Myanmar officials and for the spare parts and equipment used in the drug eradication
operations. It has been learnt from the U.S. Drug Enforcement Administration that Myanmar managed to stop $ 19 billions worth of heroin from reaching the streets of western countries, mainly the United States. Although the U. S. has cut off its assistance since 1988, Myanmar has without any substantial outside assistance from 1988 up to 19% prevented $ 45 billions worth of heroin from reaching the U. S. streets. At the same time, Myanmar's Tatmadaw managed to break the Mong Tai Army (MTA) of Khun Sa in the Golden Triangle area and had him surrender unconditionally. In this fight against narcotic drugs, the U.S. and the western world have not only refused to recognize and encourage Myanmar's efforts but are in fact also putting obstacles in her fight against narcotic armies by imposing an arms embargo.
