The president will address the Plenary Session of the General Debate of the General Assembly on Sept. 23.

A day earlier, first lady Laura Bush will host a White House Symposium on Advancing Global Literacy and a luncheon for spouses of heads of state, and the Bushes will host an evening reception for Heads of Delegation on Sept. 22.

Bush will also attend an event on food security, and meet with democratic activists. He will co-host an event with Iraqi President Jalal Talabani to thank coalition members for help in Iraq, the White House said.

Later in the week, Bush will host a meeting of leaders of Western Hemispheric countries that have signed free trade agreements with the United States.

"All of the president's events will stress the importance of effective multilateral action in promoting freedom and democratic governance, addressing terrorism, and reducing barriers to international trade and investment," the White House said in a statement.
