In his classic work “Prisoners of Geography,” Tim Marshall argues how geography moulds as well as restricts the decision-making process for global leaders. The same is true for South and South East Asia, where China effectively controls the world’s greatest freshwater reserves, attributable to its control over the Tibetan Plateau, the source of the majority of transboundary rivers in this region. Mighty rivers such as Mekong, Brahmaputra have been tamed through active dam building which has resulted not only into geopolitical risks for lower riparian states but have adverse impact on ecosystem sustained by these rivers. China considers these resources as sovereign right rather than shared resource which eventually became a rationale for China to evade the purview of principle of Public International Law such as in case of Mekong River Commission where China hasn’t officially joined as partner thus repudiating its stand on Mekong river (Lancang river in China) as a sovereign right.
