  • The Law On Price by Dr. Nguyen Anh Tuan, LNT & Partners

    On 6/20/2012, the National Assembly voted to adopt the Law on Price (the "LOP") in response to the public demand for an effective legal framework to control price manipulation from dominant enterprises such as gasoline, electricity, etc. The law will take effect from 01/01/2013 and repeal Ordinance No. 40/2002/PL-UBTVQH10 dated 26/4/2002 of the National Assembly Standing Committee (the "Ordinance"), which is conceived as outdated and containing certain provisions contravening the WTO’s regulation. This article describes the main features of the law and provides some insight into its potential impacts on the Vietnamese economy.
