Abbas said Arab states must pay their quotas to sponsor projects outlined in the plan, which was agreed at previous Arab summits, Wafa reported.
"We began to embody the decision on the ground, and we're seeking at the same time to find an approach to end the current conflict," Abbas said at the Arab development conference in Riyadh.
"If the Israeli government chooses to keep expanding settlements we will start using all possible ways including going to international organizations," the president added.
Abbas, who leads Fatah, pledged to work "with sincerity and conviction" to end his party's rift with Hamas and to make national reconciliation a reality on the ground.
Reconciliation will be achieved by elections, he added.
He also reiterated that Palestinians were not a party to the Syrian conflict and called on "our brothers in Syria" to keep Palestinians out of the civil war.
"We look forward to seeing harmony and peace, freedom and justice prevail countries of the Arab nation," Abbas added.
