"We can't speak now about what happened," he told a joint press conference with UN chief Ki-moon at his headquarters in the West Bank city of Ramallah.
"We discussed the issues which are always on the table; borders, Jerusalem, settlements," Abbas said.
"Until now we didn't speak about what happened (in the talks) and when there is something we shall tell you."
Ban, who arrived from Jordan, called upon Israel and the Palestinians to avoid actions which could disrupt the US-brokered negotiations, which resumed yesterday in Jerusalem after a three-year hiatus.
He "called on the Israelis and the Palestinians to have patience and do all that they can for the success of their negotiations and achieve the needed progress with the help of the international community," it said.
