Vietnam announced Wednesday it will withdraw its estimated 70,000 troops from Cambodia by the end of September, ending a costly and widely condemned 10-year occupation.

A joint statement by Vietnam, Cambodia and Laos said an international commission has been invited to oversee the pullout and guarantee an end to foreign military aid to parties to the conflict."Vietnam will withdraw all its troops from Cambodia by the end of September 1989," said the statement released by the official Cambodian news agency SPK.

In Bangkok, The Nation newspaper, quoting high-level sources, said Cambodian Prime Minister Hun Sen will announce concessions aimed at ending a decade of fighting between his government and guerrillas from a U.N-recognized coalition based along Cambodia's western border with Thailand.
