HANOI: Vietnam could export 1.29 million tonnes, or 21.5 million bags, of coffee this year, the farm ministry said on Wednesday, only slightly up on its projection of 1.25 million tonnes made earlier this month.

Coffee export revenue is expected to hit $2.85 billion, up 3.6 percent from 2011, the Agriculture Ministry said in a monthly report.

Vietnam is the world's second-largest coffee producer after Brazil and ranks first in production and export of the robusta variety.
