The United States hopes to present its long-awaited peace plan in 2018 but both Israel and the Palestinians have to be ready for it first, a White House official said on Tuesday.
Asked if the goal was to have the plan out this year, the White House official told reporters in Jerusalem: "My hope would be yes."
"It'll come out both when it's ready and when both sides are actually willing to engage on it," the official said.
The statement was echoed Tuesday by U.S. Vice President Mike Pence, who said Tuesday the timing of a U.S. Middle East peace initiative depended on the return of Palestinians to negotiations.
President Donald Trump's advisers have been working on the outlines of a plan for some time. But Palestinians have ruled out Washington as a peace broker after the U.S. president's Dec. 6 recognition of Jerusalem as Israel's capital.
"The White House has been working with our partners in the region to see if we can develop a framework for peace," Pence said on the last leg of a three-day Middle East trip. "It all just depends now on when the Palestinians are going to come back to the table."
Trump's Jerusalem move angered the Palestinians, sparked protests in the Middle East and raised concern among Western countries that it could further destabilize the region. Palestinians see east Jerusalem as capital of a future state.
Pence said in the interview that he and the president believed the decision, under which the United States also plans to move its embassy to Israel from Tel Aviv to Jerusalem, would improve peacemaking prospects.
A White House official acknowledged Tuesday that the United States and the Palestinian leadership had not had any direct diplomatic contact since Trump's Jerusalem declaration.
Hanan Ashrawi, a senior official at the Palestine Liberation Organization, said the Trump administration had dealt a death blow to any prospect for peace.
"The extremist positions of this U.S. administration and the biblical messianic message of Pence not only disqualified the U.S. as a peace broker but created conditions of volatility and instability in the region and beyond," Ashrawi said.
Pence discussed the Jerusalem issue during talks with Egyptian President Abdel-Fattah el-Sissi on Saturday and Jordan's King Abdullah on Sunday. He said the two leaders had agreed to convey to the Palestinians that the United States was eager to resume peace talks.
"We want them [the Palestinians] to know the door is open. We understand they're unhappy with that decision but the president wanted me to convey our willingness and desire to be a part of the peace process going forward," Pence said.
Asked if the Egyptians and Jordanians had agreed to pressure the Palestinians to return to talks, Pence said: "I wouldn't characterize it as that."
Following his meeting with Prime Minister Benjamin Netanyahu, Pence said he admired Netanyahu's leadership and appreciated his friendship.
Asked if he hoped for the prime minister's re-election, Pence said: "I'm a strong supporter of Benjamin Netanyahu, but I don't get a vote here."
The vice president also pressed European leaders to heed Trump's call to forge a follow-up agreement to the Iran nuclear deal established under President Barack Obama's administration.
"At the end of the day, this is going to be a moment where the European community has to decide whether they want to go forward with the United States or whether they want to stay in this deeply flawed deal with Iran," he said.
Asked if he thought the United States would succeed in getting that kind of agreement with its European allies, Pence said: "We'll see."
