Radio Free Asia (RFA) says the government order was dated May 8 and publicly released the following day. It said the ministry has taken note of the existence of forest and land-clearing, as well as the seizure of forest land for private ownership.
RFA said the order appears to be in reaction to a report from the Environmental Investigation Agency (EIA). The London-based group released the report on April 8.
The group described a major tree-clearing operation and timber export business in Cambodia. It said corrupt Cambodian government officials and Vietnamese companies started the business last year in the northeastern province of Ratanakiri.
The EIA report accuses corrupt officials and members of Vietnam's armed forces of removing large numbers of illegally cut trees from Cambodia. It noted their removal violates Cambodia's ban on timber exports to Vietnam. The Cambodian government has banned such exports for over 30 years.
The report is called "Repeat Offender: Vietnam's Persistent Trade in Illegal Timber." It estimates that over 300,000 cubic meters of hardwood logs have been taken from Cambodia's national parks and shipped to Vietnam.
Much of the wood is valuable Siamese rosewood, which is listed as "vulnerable" by the International Union for Conservation of Nature. Any wood listed as "vulnerable" is one step away from being "endangered."
The EIA says timber smugglers are paying bribes to border agents in both countries. In return, the agents permit shipment of the trees to Vietnam.
The report said more than $13 million in unlawful payments have been made to Cambodian officials since last November.
Ouch Leng is an investigative reporter and activist. He has reported on illegal logging operations and corruption in Cambodia's Prey Lang Forest. He won the 2016 Goldman Environmental Prize for his reporting.
He said it is a good thing for the Cambodian government to be concerned about illegal timber trade. But he does not think the government will be able to stop it.
"That's because the people who are involved in the illegal logging business are members of the government or the armed forces," he said.
Seng Sok Heng is another critic of the Cambodian government. He said he thinks some law enforcement agents will continue accepting money and permit the smuggling to continue.
Seng Sok Heng是另一位柬埔寨政府的批评人士。他说，他认为一些执法人员会继续收受贿赂并允许木材走私行为继续下去。
He's said, "It's too little, too late now. Such action should have been taken much earlier."
