They also offer preferential loans to develop projects of production and storage facilities for such purpose. These loans could be up to 70% of project value and last at most 12 years. The financial support provided for these loans is the difference of payment between interest rate of commercial loans and that of state credit for development (currently 10.8% per annum). These preferential loans are channelled through five designated state-owned commercial banks, namely VBARD, Mekong Housing Bank, Joint Stock Commercial Bank for Investment and Development of Viet Nam, Viet Nam Joint Stock Commercial Bank for Industry and Trade and Joint Stock Commercial Bank for Foreign Trade of Viet Nam (MARD, 2014b).
