King Norodom Sihamoni of Cambodia has pardoned his half brother, Prince Norodom Ranariddh, who was convicted last year of embezzling $3.6 million from his own political party, Funcinpec, by selling the party’s headquarters. Prince Ranariddh was co-prime minister until he was ousted in a coup in 1997 by Hun Sen, the other co-prime minister, who is now prime minister. The pardon allows Prince Ranariddh to return home from Malaysia, where he has been living to avoid an 18-month prison term. He now heads a new party, the Norodom Ranariddh Party, which won two seats in this year’s parliamentary election. King Sihamoni and Prince Ranariddh are sons of Norodom Sihanouk, who retired as king in 2004.
