The two leaders had a telephone conversation on Friday and, according to the White House, Trump stressed Washington's willingness to work closely with both Palestinian and Israeli leadership to make a peace deal possible.
"The talks with US President Trump was positive, as the president affirmed his commitment to peace… and invited President Abbas to visit the White House, to visit him to achieve that goal," Saeb Erekat said.
"I cannot speak for the US president, but we, as the Palestinian side and the Arab side, are doing all we can to stop the occupation and create a Palestinian state," Erekat said.
Erekat refrained from any forecasts on Abbas' visit and the resumption of the negotiations.
"All these issues will be discussed and we will see what the result will be. We do not want to get ahead of ourselves," the official said.
Palestinians seek diplomatic recognition for their independent state on the territories of the West Bank, including East Jerusalem, which is partially occupied by Israel, and the Hamas-controlled Gaza Strip.
