Organized in 1982 from two other agencies, CSA became responsible for stabilizing grain prices, maintaining a security food stock through market intervention, monitoring production and food deficits, and distributing food aid. SONIMEX began operations in 1966 as a government-controlled joint venture. The company held a monopoly on the imports of basic commodities (principally rice, tea, sugar, and tomato paste), which it resold to private interests for the retail trade.
