Cambodia's Vietnamese-installed government Wednesday agreed to a truce that would smooth the way for talks aimed at ending the country's 12-year-old civil war.

A day earlier, the non-communist forces of Prince Norodom Sihanouk - leader of the three-party guerrilla coalition - accepted the joint appeal by the French and Indonesian foreign ministers and U.N. Secretary General Javier Perez de Cuellar. Vietnamese Deputy Foreign Minister Le Mai endorsed it.However, the other two rebel groups - including the notorious Communist Khmer Rouge - had yet to respond.
