Introduction A L'histoire Contemporaine Du Viet Nam: De La Reunification Au Neocommunisme (1975-2001). This introduction to the history of Vietnam since the communist victory and the country's reunification in 1975 divides the period into three stages.  1975-1980 - both illusion and disappointment and triumphant optimism. The 1980s - when a balance was being sought in many areas between the rigour of socialist realism and necessary tolerance.  The 1990s - when active reforms led up to the neo-communist declarations of spring 2001. Bibliography. In French.
