He said he wanted to end speculation that Israel has a secret agenda for the West Bank, including additional withdrawal from the area.
Sharon told an economic conference, "We have no better plan for the future of Israel" than the present one and no change is anticipated, Ha'aretz reported.
Rumors started on Wednesday when two Sharon confidants raised the possibility that, in the event of diplomatic deadlock, Israel could unilaterally withdraw from parts of the West Bank and annex other areas. The statements caused a political firestorm and harsh U.S. reaction.
Sharon insisted that idea does not represent his views.
Israel completed its withdrawal from the Gaza Strip and the northern West Bank less than a month ago.
