Sanader was in Washington on Monday to attend, in his capacity as president of the Croatian Democratic Union (HDZ) party, a conference of the International Democratic Union, the association of over 80 Conservative, Christian Democratic and similar centrist and centre-right parties. During the meeting the HDZ is expected to be admitted to the organisation as a member.
US President George W. Bush will receive conference participants, including Sanader, in the White House on Tuesday, which Biscevic said would be an opportunity for a brief conversation about Croatian-US relations.
"According to some indications, President Bush has personally requested that Prime Minister Sanader attend the meeting," Biscevic said.
The State Secretary said that the purpose of Sanader's visit to the US was "to strengthen bilateral relations with the world's largest power" and that the relations between the two countries had been "stable" for more than a year.
"There is no reason for any speculation about oscillations in Croatian-US relations," Biscevic said.
He added that there were some political topics that were attractive to the media, such as the desire of the United States to sign an agreement on the non-extradition of Americans to the International Criminal Court, which Croatia refuses to do.
Biscevic said that there had been no change in the position of the two countries on the signing of the agreement, which is known as the Article 98 Agreement.
Biscevic said that Croatia was not in a position to change its "principled position" regarding the application of the Rome Statue and that it was not under pressure from the US to do so.
"Our aim is to assure the US as the leading member of the NATO alliance that by implementing the third cycle of the Membership Action Plan we are moving towards NATO at an accelerated pace, and then we will also address the Article 98 issue," Biscevic said.
On Tuesday, Sanader is also scheduled to meet Stephen Hadley, US Presidential Adviser on National Security, members of the Croatian congressional caucus, and members of the managing board of the firm General Dynamics, while Biscevic is due to meet Pierre-Richard Prosper, Ambassador-at-Large for War Crimes Issues.
