Despite repeated threats to punish countries that do not agree with United States policy in the Middle East, the Trump administration is set to boost aid to Jordan by more than $1 billion over the next five years.
In December, Mr Trump threatened to cut off financial aid to countries which voted in favour of a United Nations resolution calling for the USA to withdraw its decision to recognise Jerusalem as Israel's capital. It's been under development for a number of months.
Theresa May said at the time: "We disagree with the U.S. decision to move its embassy to Jerusalem and recognise Jerusalem as the Israeli capital before a final status agreement".
Tillerson said the proposal is "fairly well advanced" but would not comment on when the administration might put it forward.
The administration has so far been tight-lipped about the plan and Tillerson declined to offer details.
The United States has also forged closer ties with Saudi Arabia and other Gulf Arab states while taking a tougher line against Iran since Trump took office.
The spokesman pointed out that Sisi and Tillerson discussed various regional issues, including the situation in Libya and Syria, in addition to efforts exerted to reach a political settlement to the ongoing crises. The administration later announced an accelerated timetable for moving the embassy to Jerusalem from Tel Aviv by the end of next year.
Jerusalem is home to sites holy to Muslims, Jews and Christians. The king has warned that Trump's decision could undermine stability and fuel radicalism.

Tillerson arrived in Amman late Tuesday as part of a wider Middle East tour that has already taken him to Egypt and Kuwait.
