Layers of regulation in transboundary water governance: exploring the role of third states in the Lancang–Mekong

This paper first provides a theoretical tour d’horizon of this legal problématique, identifying a series of problems and possible solutions based on the Vienna Convention on the Law of Treaties. The practical consequences of this problématique will then be explored in the context of the Lancang–Mekong River, and the interaction between the various legal frameworks at play.
