Ex-deputy trade minister Mai Van Dau is being charged for corruption in a scandal over exports of textiles and clothing to the US, according to Vietnamese state-controlled media.

Dau is the top ranking among a group of officials involved in the case in which himself and Le Van Thang, former deputy director of the ministry's Import-Export Department, are said to have taken bribes worth hundreds of thousands of dollars from companies affected by a US exports quota.

About sixteen other people are reported to have been charged with fraud and bribery connected with the case, and will stand trial along with Dau and Thang.

The US introduced a quota of $1.7 billion on Vietnam's textile and clothing exports to the US two years ago, causing anxiety among producers.

Vietnam's textile industry is its second-biggest source of export revenue after crude oil.
