In 1999, following the United Nations-sponsored act of self-determination, Indonesia relinquished control of the territory. As ''Timor-Leste'', it became the first new sovereign state of the 21st century on 20 May 2002 and joined the United Nations and the Community of Portuguese Language Countries. In 2011, East Timor announced its intention to become the eleventh member of the Association of Southeast Asian Nations (ASEAN). It is one of only two predominantly Catholic nations in Southeast Asia, the other being the Philippines, as well as the only country of Asia to be located completely in the Southern Hemisphere.
