The State Audit Office of the Kingdom of Thailand hosted the 7th Seminar on Environmental Auditing and 6th Working Meeting of ASOSAI WGEA from 29th to 31st January 2018 in Khao Yai National Park, Nakhon Ratchasima, Thailand. 57 participants from 24 ASOSAI members attended this meeting with active contribution in sharing environmental auditing engagements in their countries. Apart from presentation of overall achievement, this forum also allows participants to discuss on “IT Application in Environmental Audit", which will hopefully enhance IT involvement in environmental auditing. The 6th Working Meeting of ASOSAI WGEA also approved the launch of cooperative audit on water environmental protection with 12 SAIs expressed their intentions to join, of which SAI Thailand volunteers to be the leader.
