Vietnam has ratified a United Nations treaty on transboundary rivers, and it is time for other Mekong countries to do the same.
On May 19th, Vietnam became the 35th country to ratify the 1997 UN Convention on Non-navigational uses of International Watercourses (UNWC). This is an important global milestone because the treaty required 35 ratifications to enter into force. It will now do so on August 17, 2014.
