After Ethiopia launched an offensive to break the stalemate in early May 2000, the Security Council passed UNSCR 1298 on 17 May 2000, imposing a one-year arms embargo on both states, demanding an immediate ceasefire and a return to peace talks. Ethiopia effectively won the war eight days later, capturing all the contested territory. After Eritrea declared its intention to withdraw from the Ethiopian territory it still occupied along the border, Ethiopia formally declared the war over on 25 May. Ethiopia effectively occupied 25% of Eritrean territory and had displaced an estimated 650,000 people. Both countries accepted the terms of the OAU sponsored Algiers Agreement of 18 June 2000 that established a temporary security zone along the disputed border, called for troop withdrawals, forwarded the dispute to the Hague Boundary Commission, and laid the basis for a UN PKO (UNMEE). A formal peace agreement was signed on 12 December 2000, and on the eve of the scheduled termination of the sanctions, a Presidential Statement declared the Council's decision not to extend the arms embargo after 16 May 2001.
