German Chancellor Gerhard Schroeder left Berlin for Washington Wednesday evening to pay a two- day visit to the United States.
He will meet with U.S. President George W. Bush on Thursday on the leading role of the international peace-keeping force in Afghanistan.
Britain is leading the force at present but will hand over its leading position in April.
Germany has been asked by the Afghan government, reportedly also by the United States, to take up the leading role after Britain.
However, Germany has expressed its unwillingness to lead the force, saying the German Armed Forces don't have enough capacities to do that.
The international peace-keeping force in Macedonia is under German leadership at present. Germany has ruled out the possibility to lead the force in Afghanistan as long as it led the troops in Macedonia.
The two leaders are also scheduled to hold talks on the planned NATO easternward expansion and the situation in the Middle East.
On Friday, Schroeder will deliver a speech on economic globalization at the World Economic Forum meeting in New York.
