Abbas has performed diplomatic duties, presenting a moderating contrast to the PLO's "revolutionary" policies. Abbas was the first PLO official to visit Saudi Arabia after the Gulf War in January 1993 to mend fences with the Gulf countries after the PLO's support of Iraq during the Persian Gulf War strained relations. In the Oslo I Accord, Abbas was the signatory for the PLO on 13 September 1993. He published a memoir, "Through Secret Channels: The Road to Oslo" (1995).
