Jordan's foreign minister has warned the US of "dangerous consequences" if it recognises Jerusalem as the capital of Israel.
Ayman Safadi said he had told US Secretary of State Rex Tillerson such a declaration would trigger great anger in the Arab and Muslim world.
Speculation is mounting that President Donald Trump will announce the move soon, fulfilling an election pledge.
In a tweet, Safadi said: "Spoke with #US Secretary of State Tillerson on dangerous consequences of recognising Jerusalem as capital of Israel. Such a decision would trigger anger across #Arab #Muslim worlds, fuel tension and jeopardise peace efforts."
There was no public response from the US State Department.
During his election campaign, Donald Trump promised to move the US embassy from Tel Aviv to Jerusalem
Palestinian President Mahmoud Abbas is trying to rally international support to persuade Trump not to make the announcement.
His office said he made phone calls on Sunday to world leaders including French President Emmanuel Macron and Turkish President.
