King Norodom Sihamoni used a speech during celebrations marking the 60th anniversary of Cambodia’s independence from France on Saturday to call for unity amid growing concerns over the long-term harmony of the nation since July’s disputed national election. Government officials, military officers and foreign diplomats turned out to a ceremony, which opened at Independence Monument at 7 a.m. and closed two hours later at the Royal Palace, to commemorate then-King Norodom Sihanouk’s 1953 declaration of independence from French colonial control.
