Representatives of Afghanistan's rival tribes and factions are now expected to meet in Bonn, Germany, on Monday to discuss sharing power in post-Taleban Afghanistan.
The German Foreign Ministry says it has switched the meeting place from Berlin to Bonn.
The participants in the talks are expected to include United Nations officials and observers. Germany, though it is hosting the conference and providing security, is not a partner in the sessions.
Earlier, the United Nations said four Afghan groups agreed to take part in the conference in an effort to forge a transitional administration for the war-torn country.
A spokesman for Afghanistan's Northern Alliance has said no former Taleban leaders will be accepted at the meetings.
Meanwhile, British Foreign Secretary Jack Straw is traveling to Iran and Pakistan for talks with two of Afghanistan's neighbors that have concerns about the country's future.
Mr. Straw is leaving today (Wednesday) for talks in Tehran on Thursday and Islamabad the following day.
Iran and Pakistan both have long borders with Afghanistan and have experienced a massive amount of refugees entering their countries from the war.
It will be the foreign secretary's second visit to the region since the September 11th attacks in the United States.
