The logging ban went into force on 31 March 1994, but trees continued to be felled and a new stockpile of timber was created. Ranariddh and Hun Sen gave special authorisation for the lumber to be exported to North Korea. They would continue the practice of periodically lifting export bans and granting special approvals to clear stocks of fallen timber on an on-and off-basis until Ranariddh's ouster in 1997. According to Canadian geographer Philippe Le Billon, Ranariddh and Hun Sen tacitly supported continued Khmer Rouge logging activities as it provided a lucrative backdoor source of cash revenue to finance their own political activities. Under Ranariddh's co-administration, Malaysia's Samling Berhad and Indonesia's Macro-Panin were among the largest beneficiaries of government contracts, as these two logging companies, in 1994–1995, secured rights to log 805,000 hectares and 1.4 million hectares of forests, respectively.
