ASEAN-WEN is an integrated network among law enforcement agencies and involves CITES authorities, customs, police, prosecutors, specialized governmental wildlife-law enforcement organizations and other relevant national law enforcement agencies from across the ASEAN region. ASEAN-WEN operates on national and regional levels. Each country is expected to establish a national inter-agency task force of police, customs, and environmental officers. The Kingdom of Thailand, the Philippines, Myanmar, Indonesia and Malaysia have established fully functioning national task forces. These task forces are the enforcing mechanisms of a regional network committed to stopping national and trans-regional illegal wildlife trade. Law enforcement officers in national task forces receive trainings on investigations, species identification and wildlife laws to improve their capacity and expertise in wildlife crime. National task forces are responsible for stopping wildlife crime in their country and coordinating with counterparts across the region to stop cross-border wildlife crime. Some national task forces are also focal points of ASEAN-WEN, while some are interagency coordination units tasked to combat the larger environmental crimes and illegal logging.
ASEAN-WEN’s Terms of Reference adopted by the First Meeting of the ASEAN-WEN in Bangkok, 25 May 2006 mandates ASEAN Member States “to establish at the national level an ASEAN-WEN committee consisting of officials from relevant organizations, which shall be responsible for coordinating each member country’s activities in relation to wildlife-law enforcement and the combating of illicit harvesting of and trade in wild fauna and flora.” Many National Task Forces have evolved since then and some have expanded its remit to illegal logging, marine enforcement and the environmental crimes in general.
