The pontiff is to make a brief visit to Israel and the Palestinian territories from May 25, his first to the Holy Land, Israeli newspaper Yediot Aharonot said last week.
"As we begin preparations for the visit of His Holiness Pope Francis next year, we call upon pilgrims from all over the world to come and experience Palestine and our Holy Sites," Abbas said.
The pope's visit "will be a good opportunity for Christians from all over the world to become closer to their sisters and brothers in Palestine."
During the visit, the pope will celebrate a high mass in Bethlehem, the traditional birthplace of Jesus, local media reported.
The trip has yet to be officially confirmed by the Vatican, although the announcement could come in the weeks after Christmas.
But a Vatican spokesman has said officials from the church have made a site visit.
Pope Francis was invited to visit the Holy Land by Israeli President Shimon Peres in April, and by Abbas, who met him on October 17.
