Israel’s prime minister, Benjamin Netanyahu, said on Sunday that he would offer US President Donald Trump’s Middle East peace plan open and fair consideration, while the Palestinian president, Mahmoud Abbas refused the proposal.

The two leaders were speaking separately about Trump’s plan for the first time since details of its initial economic periods were unveiled.

The Trump administration is formally revealing the economic portion of the program this week at a workshop in Bahrain, which it wishes will aid the economy of Palestinian territories and of the Middle Eastern region. The political section of the plan will be disclosed later.

“We’ll hear the American proposition, hear it fairly and with openness. And I cannot understand how the Palestinians, before they even heard the plan, reject it outright,” Netanyahu said while traveling through the area with touring U.S. National Security Adviser John Bolton. “Under any peace agreement our position will be that Israel’s presence should continue here, for Israel’s security and for the security of all,” Netanyahu said.

Husam Zomlot, head of the Palestinian Mission in London, wrote on Twitter, “The Jordan Valley is Palestine’s strategic reservoir & the most vital area for a prosperous Palestinian economy: Water, fertile lands, minerals, Dead Sea and heritage sites”

The Dead Sea and Jorden Valley area cover around 30.0% of the West Bank. Palestinians said that it is an integral part of the land that they want for a future state. “Money is important. The economy is important. But politics are more important. The political solution is more important,” Abbas said in the West Bank city of Ramallah.

“We welcome all those who wish to help us, whether it be in Manama or anywhere else. But for now, we reject the deal of the century,” he added.
