Sihanouk maintained a monthly bulletin in which he wrote commentaries on political issues and posted old photos of Cambodia in the 1950s and 1960s. In 1997 a character known by the name of "Ruom Rith" first appeared in his monthly bulletin, expressing critical comments on Hun Sen and the government. Hun Sen became offended by Ruom Rith's criticisms, and on at least two occasions in 1998 and 2003 persuaded Sihanouk to stop publishing his comments. According to Ranariddh, Ruom Rith was an alter ego of Sihanouk, a claim which the latter vehemently denied. In July 2002, Sihanouk expressed concern over the absence of detailed constitutional provisions over the organization and functioning of the Cambodian throne council. When Hun Sen rejected Sihanouk's concern, the latter followed up in September 2002 by threatening to abdicate, so as to force the throne council to convene and elect a new monarch.
