On 14 December 2022, OLAF and the Ministry of Finance of the Socialist Republic of Viet Nam signed a working arrangement, which will facilitate cooperation between OLAF and the Vietnamese customs services. The arrangement also implements the protocol on mutual administrative assistance in customs matters that was concluded between the EU and Viet Nam in the framework of their free trade agreement in 2019.

The arrangement covers the exchange of information between OLAF and Viet Nam Customs in connection with the fight against illicit trade in tobacco products, counterfeit goods, origin fraud, customs valuation fraud, illicit transhipment of waste and endangered species. It also regulates assistance and cooperation in operational activities and training as well as the establishment of contact points on each side.
