World Food Program officials said Mr. Morris was to discuss ways to improve the U.N. agency's work in Burma.
The WFP denied press speculation that Mr. Morris was carrying a private message from U.N. Secretary General Kofi Annan to Burma's government about its political problems.
Mr. Annan has been trying to foster political reconciliation in Burma, which holds opposition leader Aung San Suu Kyi under house arrest.
Mr. Morris also met with key members of her political party, the National League for Democracy.
Mr. Morris is scheduled to leave Burma later today for Bangkok, Thailand.
