The Obama administration has renewed Washington's commitment to a two-state solution to the conflict between Israel and the Palestinians.
As a row raged over the new Israeli government's stance, the White House said Barack Obama looked forward to working with Israel's new leaders.
Foreign Minister Avigdor Lieberman has said the government will not be held by commitments made by its predecessors.
A US-hosted 2007 agreement had, he declared, "no validity".
Each side had agreed at talks in Annapolis to further discussions aimed at creating an independent Palestinian state.
But Mr Lieberman, an ultra-nationalist, argues that the accord was never ratified either by the Israeli government or parliament.
Palestinian President Mahmoud Abbas said the world should put pressure on the new Israeli government of Benjamin Netanyahu.
