	  France occupied all of Vietnam 
    by 1884. Independence was declared after World War II, but the French 
    continued to rule until 1954 when they were defeated by communist forces 
    under Ho Chi MINH, who took control of the north. US economic and military 
    aid to South Vietnam grew through the 1960s in an attempt to bolster the 
    government, but US armed forces were withdrawn following a cease-fire 
    agreement in 1973. Two years later North Vietnamese forces overran the 
    south. Economic reconstruction of the reunited country has proven difficult 
    as aging Communist Party leaders have only grudgingly initiated reforms 
    necessary for a free market.
