The Bolivarian Alliance for the Peoples of Our America （its Spanish acronym is ALBA） is a regional integration bloc fully comprised by developing countries. It is a result of the antagonism against neo-liberalism in Latin America，the long-standing quest of regional countries for deeper regional integration and the combination of nationalism and anti-Americanism. ALBA advocates a state-based integration and expects to be an alternative to the market-based integration mechanism. By developing a mechanism of maximum flexibility，it seeks to assist member countries to achieve full cooperation and integration. Currently its integration process is involved with economic，political and social fields. Economically it has issued the common currency named SUCRE and established the ALBA Bank to facilitate economic cooperation among its members. Diplomatically it has coordinated member countries to take common position on a variety of major international and regional issues. In the social field，the member countries have made a joint effort to improve education and health，contributing greatly to promote social justice.
