Trump called the Palestinian president on March 10 for the first time since his inauguration, inviting him to the White House.
"We'll decide on (the date of) this meeting as quickly as possible," Abbas told a press conference at his presidential complex in the occupied West Bank.
Abbas welcomed the visits to Ramallah of several US officials, including CIA chief Mike Pompeo in mid-February and Trump's special representative for international negotiations, Jason Greenblatt, whom he met on Tuesday.
The next major diplomatic rendezvous for the Palestinians is March 29, when the heads of states of the Arab League will meet in Jordan.
"All the eyes of the Arab states will be turned toward the capitals of the world, especially Washington to see what can be done by this administration (American) who said it wants to reach peace," said Abbas after receiving Bosnian President Mladen Ivanic.
