A statement to be presented at the end of Wednesday's U.S. - European Union summit in Vienna is expected to include pledges to respect human rights in the war on terrorism.
A draft of the statement obtained by news agencies says the battle against terror will be "consistent with our common values," including international obligations to human rights laws.
The news agencies say the draft makes no mention of U.S. run detention center in Guantanamo Bay, where hundreds of terror suspects are jailed.
Summit host Austria says it plans to make it clear to President Bush that the E.U. believes the facility must be closed.
White House National Security Adviser Stephen Hadley says Mr. Bush and the European powers will also reaffirm efforts to resolve the Iranian nuclear crisis, but says no major announcement are expected.
Summit participants also plan to discuss trade with negotiators struggling to meet a year-end deadline for a new world trade agreement.
Thousands of demonstrators are expected in Vienna to protest Mr. Bush's visit, the war in Iraq, and some tactics in the war against terrorism.
After Vienna, Mr. Bush heads to Budapest for ceremonies marking the 50th anniversary of the Hungarian Revolution.
