Thai Prime Minister Abhisit Vejjajiva is to visit Cambodia on June 12, during which he will formally hand over seven Angkorian artifacts that were smuggled into Thailand nearly a decade ago, Thai press reports said Wednesday. The artefacts are among 43 pieces seized in 2000 when they were illegally brought across the border. Government spokesman Khieu Kanharith said Wednesday he had seen press reports of the proposed visit but has not yet received any official confirmation.
