A sale of U.S. grain to North Korea stalled last week over terms of the deal.
North Korea, which is experiencing severe food shortages, is negotiating to buy 500,000 tonnes of wheat and rice from Cargill Inc. Officials say the cash-strapped communist country wants to buy the grain on credit, but Cargill wants cash.
The snag caused postponement of a meeting between U.S. and North Korean diplomats at the United Nations called to discuss the possibility of North and South Korea formally ending four decades of hostility.
