Israel's Prime Minister Ariel Sharon has rejected his Palestinian counterpart's demand that Israel stop building a controversial barrier through the West Bank.
Palestinian Prime Minister Ahmed Qurie has said Israel must stop work on the barrier before he would meet Mr Sharon for talks on reviving a the "road map" to peace plan.
"I hereby notify you that no condition shall be accepted ... regarding the cessation of the fence, dismantling of the fence and other fabrications," Mr Sharon was quoted as saying in the official report on today's cabinet meeting.
Earlier, Mr Qurie urged the United States to press Israel to stop building the barrier.
Israel says the fence is to stop suicide bombers. Palestinians say that the barrier of concrete and razor wire is designed to annex land occupied since the 1967 war.
"We are willing to meet our obligations and we are committed to implementing the road map," said Mr Qurie after meeting his Jordanian counterpart Mr Faisal al-Fayez.
"But we also want the US to pressure the Israeli government to stop its violations, including [building] the segregation wall and the settlements," Mr Qurie said.
He was speaking before talks with Jordan's King Abdullah, who is due to visit Washington this week. Palestinian and Jordanian officials say the king will convey a message from the new Palestinian cabinet which will touch on the possibility of a new Palestinian truce.
King Abdullah said in a statement that continued settlement and work on the separation barrier were complicating efforts to revive talks and threatened the entire peace process.
Senior US envoy Mr William Burns after held meetings in the region over the weekend, reiterated US concerns about the barrier to The Jordanian Prime Minister.
A recent US decision to cut loan guarantees to Israel over the barrier signalled renewed interest in peacemaking from Washington.
Mr Burns is due to hold talks with Mr Sharon in Jerusalem later today.
