Burma has imposed a six-month ban on exports of rice. Sources in Rangoon say the decision is aimed at avoiding public discontent by lowering domestic prices.
Since the ban took effect on January first, prices have fallen by 20 to 40 percent, sparking fears among farmers.
Exporters may be subject to legal action from foreign importers who have placed large orders of rice, only to have them canceled.
Burma's military government has not intervened in the rice trade since April last year, when it lifted controls on rice exports.
Rice is Burma's main agricultural product, as well as one of its main sources of foreign currency.
