In 1999, Libya fulfilled one of the UNSCR requirements by surrendering two Libyans suspected in connection with the bombing for trial before a Scottish court in the Netherlands. One of these suspects, Abdel Basset al-Megrahi, was found guilty; the other was acquitted. Al-Megrahi's conviction was upheld on appeal in 2002. In August 2003, Libya fulfilled the remaining UNSCR requirements, including acceptance of responsibility for the actions of its officials and payment of appropriate compensation to the victims' families. UN sanctions were lifted on September 12, 2003. U.S. International Emergency Economic Powers Act (IEEPA)-based sanctions were lifted September 20, 2004.
Gaddafi's Islamic Call Society gave the Anglican Church of Christ the King in Tripoli a church building on the downtown square to compensate for the one lost at the time of the 1969 Revolution. The government paid for all the renovations and repairs, and provided housing for the vicar. <ref>[http://www.arabwestreport.info/year-2001/week-19/8-libyan-government-supports-anglican-church-tripoli The Libyan government supports the Anglican church in Tripoli,] Munir Hanna Anis Armanius, Religious News Service from the Arab World, May 16, 2001. </ref>
On December 19, 2003, Libya publicly announced its intention to rid itself of weapons of mass destruction (WMD) and Missile Technology Control Regime (MTCR)-class missile programs. Gaddafi cooperated with the U.S., the U.K., the International Atomic Energy Agency, and the Organization for the Prohibition of Chemical Weapons toward these objectives. Libya has also signed the IAEA Additional Protocol and has become a State Party to the Chemical Weapons Convention. These were important steps toward full diplomatic relations between the U.S. and Libya.
