• n order to support growth in agricultural production, there has been an increasing use of fertilisers in Vietnam. According to the Vietnamese Ministry of Industry and Trade, Vietnam spent US$ 964 million importing over 3.6 million tonnes of fertilizers between January and September 2017, posting respective year-on-year increases of 21 per cent and 17.8 per cent. The fertilizers, mostly urea, Ammonium Sulfate, Potassium, Diammonium Phosphate and Nitrogen-Phosphorous-Potassium fertilizers, were imported mainly from China, Russia, Indonesia, Canada and Japan.
• Vietnam imports almost 50 to 60 per cent of its fertilisers, making it one of the largest importers in the world. (Source: VietinBankSc, Industry Report: Fertilizers manufacturing in Vietnam ).
