Azali failed to consolidate power and reestablish control over the islands, which was the subject of international criticism. The African Union, under the auspices of President Thabo Mbeki of South Africa, imposed sanctions on Ndzuani to help broker negotiations and effect reconciliation. Under the terms of the Fomboni Accords, signed in December 2001 by the leaders of all three islands, the official name of the country was changed to the Union of the Comoros; the new state was to be highly decentralised and the central union government would devolve most powers to the new island governments, each lead by a president. The Union president, although elected by national elections, would be chosen in rotation from each of the islands every five years.
