"Aid officials are worried that the United States might not make its annual contribution to a United Nations food drive for North Korea. The U.S. has been one of the largest suppliers of food to the impoverished nation, last year providing 50,000 tons. It has not yet indicated whether it will make a pledge this year, said Anthony Banbury, Asia director of the U.N. World Food Program. "I think there is a real split in the U.S. government on whether conditions are ripe" for a contribution this year, said Banbury, who met with reporters Friday in Seoul."
