China’s practice on the non-navigational uses of transboundary waters: transforming diplomacy through rules of international law

China’s abundant transboundary water resources face new challenges as demands increase, internally and externally. As China seeks new ways to cooperate with its riparian neighbours, more attention is being paid to international water law in the evolving diplomatic practice across the region. China’s (mostly) bilateral transboundary water cooperation is here characterized as ‘responsive diplomacy’. This paper explores China’s state practice in this context and concludes by recommending that it moves from ‘responsive’ towards ‘preventive’ diplomacy. The author offers strategic and policy responses in order to effect this change.
