From 1969 to 1995, Cambodia's forest cover shrank from 73% to 30–35%. Similarly, Vietnam lost nearly three million hectares of forest cover from 1976 to 1995. In 1992, Khmer Rouge became internationally isolated. The United Nations Security Council banned all exports of Cambodian timber in November of that year. Efforts to create a neutral electoral environment led to the establishment of the United Nations Transitional Authority (UNTAC) in Cambodia. The move was implemented in January 1993. In the same year, the Vietnamese issued a logging ban, driving the Khmer Rouge to logging illegally. Illicit exports from Cambodia to Vietnam was worth US$130 million each year.
