In 1929, a British-sponsored treaty between Egypt and some Nile basin colonies, without the participation of Ethiopia, awarded Egypt the right to veto any project that it deems threatening to its water share. Recently, however, Ethiopia announced the Grand Ethiopian Renaissance Dam project, which would allow it to better exploit its water resources, rejecting the old treaty and stressing that it wasn't a member back then. According to the Egyptian authorities, the dam, if built, would negatively affect Egypt's water share, estimated at 57 percent of the Nile waters. Ethiopia turned down several requests from Egypt to pause the construction, furthering tensions between the two countries.
