Sihanouk went into exile again and in 1981 formed FUNCINPEC, a resistance party. The following year, he became president of the Coalition Government of Democratic Kampuchea (CGDK), a broad coalition of anti-Vietnamese resistance factions which retained Cambodia's seat at the United Nations, making him Cambodia's internationally recognized head of state. In the late 1980s, informal talks were carried out to end hostilities between the Vietnam-supported People's Republic of Kampuchea and the CGDK. In 1990, the Supreme National Council of Cambodia was formed as a transitional body to oversee Cambodia's sovereign matters, with Sihanouk as its president. The 1991 Paris Peace Accords were signed and the United Nations Transitional Authority in Cambodia (UNTAC) was established the following year. The UNTAC organized the 1993 Cambodian general elections, and a coalition government, jointly led by his son Norodom Ranariddh and Hun Sen, was subsequently formed. He was reinstated as Cambodia's king. He abdicated again in 2004 and the Royal Council of the Throne chose his son, Sihamoni, as his successor. Sihanouk died in Beijing in 2012.
