Answer
In 2001, Ranariddh renounced his interest in the Cambodian throne. This decision was likely motivated by a combination of factors, including his desire to pursue a career in politics and his recognition that his half-brother, Sihamoni, was the more popular choice to succeed their father, King Norodom Sihanouk. Ranariddh's renunciation paved the way for Sihamoni to become king in 2004.
