Abbas competed with the Jordanian team at the
FIBA Asia Championship 2007 and
FIBA Asia Championship 2009. In 2009, Abbas helped the Jordanian team to a national best third-place finish by averaging 13.8 points and a team-leading 8.8 rebounds per game. The third-place finish meant that
Jordan qualified for its first ever
FIBA World Championship. There, he averaged 15.2 points and 8.4 rebounds per game. Jordan made its return to the FIBA World Cup in
2019. In 2021, Abbas announced that he would be retiring from the national team. Nearly a year later, coach
Wesam Al-Sous convinced him to re-join the team for the
2022 FIBA Asia Cup. At the age of 39, Abbas made the roster for the
2023 FIBA World Cup. He was the second-oldest player to compete in that tournament behind
Marcelo Huertas. However, he went back to Jordan during the tournament due to an urgent family health situation. ==References==
