Sihanouk left in November 1992 to seek medical treatment in Beijing, where he stayed for the next six months until his return to Cambodia in May 1993, on the eve of elections. While in Beijing, Sihanouk proposed a Presidential system government for Cambodia to then-UN secretary-general Boutros Boutros-Ghali, but soon dropped the idea after facing opposition from the Khmer Rouge. When general elections were held, FUNCINPEC, now headed by Sihanouk's son Norodom Ranariddh, won, while the Cambodian People's Party (CPP) headed by Hun Sen came in second. The CPP was unhappy with the election results, and on 3 June 1993 Hun Sen and Chea Sim called on Sihanouk to lead the government. Sihanouk complied, and announced the formation of a Provisional National Government (PRG) headed by him, with Hun Sen and Ranariddh as his deputies. Ranariddh was surprised at Sihanouk's announcement, as he had not been informed of his father's plans, and joined Australia, China, the United Kingdom, and the United States in opposing the plan. The following day, Sihanouk rescinded his announcement through a national radio broadcast.
