Panama's official counternarcotics cooperation has historically been excellent. For example, officials of the US Drug Enforcement Administration praised the role of Manuel Noriega prior to his falling-out with the US over his own drug dealing. The Panamanian Government expanded money-laundering legislation and concluded with the US a Counternarcotics Maritime Agreement and a Stolen Vehicles Agreement. The Panamanian Government has enforced intellectual property rights and concluded the very important Bilateral Investment Treaty Amendment with the US and an agreement with the Overseas Private Investment Corporation (OPIC). The Moscoso administration was very supportive of the United States in combating international terrorism.
