Interviews were conducted with U.S. Government officials involved in international narcotics control and with foreign law enforcement, military, and other officials involved in narcotics control from August 1984 through January 1985. Among the five recommendations offered for Southeast Asia are that (1) the United States should take the lead in coordinating a regional approach to the antinarcotics effort in this region, including fully using the assets of the Central Intelligence Agency to obtain intelligence in the countries having an impact on the flow of narcotics into the United States and (2) the Agency for International Development must better coordinate its internal operations concerning development assistance and antinarcotics programs. For South America, recommendations include (1) having the United States negotiate updated, workable extradition treaties with countries in that region and (2) requesting Peru and Bolivia to amend their laws to make all cocoa production illegal. Among the recommendations for Central America and the Caribbean are that the U.S. embassies should be vigilant in tracking the increased narcotics trafficking through the region and should take appropriate countermeasures. Detailed findings are given for each region, along with brief reports on individual countries.
