Sri Lanka has offered to purchase 500,000 tonnes of high-quality rice from Myanmar through a government to government contract. The offer to buy 200,000 tonnes of parboiled rice and 300,000 tonnes of white rice was made last week. Parboiled rice, or converted rice, is rice that has been partially boiled in the husk. Each year, Myanmar exports between 1.5 million and 2 million tonnes of rice.
