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. Thailand was the largest violator of UNTAC. The Thai government at the time insisted that Cambodian imported timber must have a certificate of origin approved by the governmental authorities in Phnom Penh. These certificates cost US$35 for each cubic metre of timber from Khmer Rouge operating areas. This forced the Khmer Rouge to increase prices. They learned to speak Thai and sold timber illegally to Thai timber operators, earning them over US$10 million monthly. Global Witness, an international human rights and environmental non-governmental organization (NGO) based in London, recognized these timber guerillas when they identified mass Cambodian exports. They subsequently lobbied for an amendment to the US Foreign Operations Act. The act was passed. It stated that US assistance would no longer be given to any country cooperating militarily with the Khmer Rouge. Thailand closed its borders with Cambodia the next day. Japan was the second largest offender of UNTAC, purchasing 8,000 cubic metres of timber from Cambodia. There were 46 other identified offenders including the Koreas, Singapore, and Taiwan. After timber is produced by Cambodia or the greater Southeast Asia region, these "offender" countries re-process the logs which are subsequently transferred to North America, the Middle East, and Africa for sale. PRK eventually offered the Khmer Rouge re-integration into Cambodia's national armed forces as well as reconciliation between the two parties. In August 1996, the regional command of Khmer Rouge travelled back to Phnom Penh. Pol Pot, the former Prime Minister of the Democratic Kampuchea, and his lieutenants stayed in the northern region to continue attempts at generating revenue from the extraction of natural resources. However, the group became irrelevant due to a lack of support. By 1998, Khmer Rouge had dissolved completely. In 2010, the Royal Government of Cambodia set out a forest management plan called the National Forest Programme (NFP) in order to manage Cambodia's forest industry effectively in the long-term. A number of donors had been in support of the United Nations
