The Washington Declaration is a document signed by the United States and five Central American countries (El Salvador, Guatemala, Honduras, Nicaragua, and Costa Rica) on December 20, 1989. It is a commitment to promote peace, democracy, and economic development in Central America. The Declaration is divided into four parts. The first part is a declaration of common principles and objectives to promote peace, democracy, and economic well-being in the region. The second part is a plan of action to implement the common principles and objectives. The third part is a commitment to strengthen regional security, and the fourth part is a commitment to strengthen economic cooperation between the countries. There are two other types of Washington Declaration: the Washington Declaration on Security in Central America (1992) and the Washington Declaration on Trade and Investment in the Americas (1994). The former was signed by the United States and the Central American countries to strengthen regional security and promote a secure and prosperous region. The latter was signed by the United States and the other countries of the Western Hemisphere to develop free trade and investment between the countries.
