The figures were issued at a meeting of the Mekong Delta Tourism Association held to review its activities in 2012.
In 2013, the association will focus on boosting tourism cooperation in the region and expand its tourism programmes eastwards to Long An, Tien Giang, Ben Tre Vinh Long and Tra Vinh provinces.
The famous travel website Lonely Planet last year listed Mekong Delta as one of the best value destinations in the word.
