The US has issued a plan to Israel and the Palestinians for improving security and easing restriction on movement in the Palestinian territories.
The Hawara checkpoint at Nablus is to go by 15 June
The document, which was published in an Israeli newspaper, sets out a strict timetable for implementing the plan.
It requires the Israelis to dismantle a series of checkpoints near Bethlehem, Hebron and Nablus.
And it demands that the Palestinians establish, by the end of June, a plan to stop rocket fire from Gaza.
The Palestinian chief negotiator, Saeb Erekat, welcomed the proposal, but he said the Palestinians would discuss the document further with the Americans.
There has been no immediate official Israeli comment.
The plan was written by the US security co-ordinator Maj Gen Keith Dayton, US Ambassador to Israel Dick Jones and US Consul-General in Jerusalem Jacob Walles.
Reports say it was approved by Secretary of State Condoleezza Rice, who is expected in the region again around 15 May.
Clauses of the plan are accompanied by a precise date by which they must be implemented.
