Ili River
Contamination of Balkhash originates not only locally, but is also brought by inflow of polluted water from China. China also consumes 14.5 km3 of water per year from Ili River, with a planned increase by 3.6 times. The current rate of the increase is 0.5–4 km3/year. In 2007, Kazakhstan Government proposed a price reduction for sales of Kazakh products to China in exchange for reduction of water consumption from Ili River, but the offer was declined by China.
