Defiant of Egypt’s historic monopoly over its flow, Ethiopia is pushing ahead with a controversial plan to build a massive dam on the Nile river. Egypt and Sudan have maintained control of the Nile through a series of laws originally brokered by colonial powers in 1929.

But last May, six upstream countries signed a legally binding document that dispossessed Egypt of its right to veto decisions regarding the Nile’s distribution. Buoyed by President Hosni Mubarak’s recent ouster, and undaunted by criticism, Ethiopia insists that it will proceed with its plan even without international support.

At a recent news conference, Ethiopia’s Water and Energy Minister Alemayehu Tegenu explained that construction of the dam near the Ethiopian and Sudanese border is expected to start soon, Reuters reports.

This despite widespread opposition to the project, which Minister Tegenu suspects is a direct result of Egypt’s campaign to prevent the dam’s construction.
