Information summarizing the objectives of a visit of the FSLN delegation, headed by Baiardo Arse [name is spelled phonetically], to Bulgaria. The visit, which took place from 28 June to July 3 1983, aimed at exchanging information and ideas on ways to reform FSLN, in order to transform the Front into an avant-garde Marxist-Leninist party.
The document describes the political and economic pressure exerted by the Reagan administration on a number of Central and Latin American countries, in order to decrease the support for the Front and other leftist revolutionary movements. According to the information FSLN responded to these measures by consolidating and strengthening its army, and national militia; maintaining transparency and political pluralism; strengthening the cooperative and state economic sector, and redirecting trade to new markets, mainly in the socialist community.
