CAIRO (AP) — Egypt’s foreign minister says the U.S. will host talks over a growing water dispute over Ethiopia’s soon-to-be-finished Blue Nile dam, which Egypt claims threatens its water supply.

Sameh Shoukry told reporters Tuesday that the Trump administration has invited representatives from Cairo, Addis Ababa and Sudan for talks on Nov. 6.

The development comes three weeks after talks between the Egypt, Ethiopia and Sudan failed to resolve their differences over Ethiopia’s dam project.

Egypt says filling the dam’s giant reservoir will severely diminish its portion of downstream water, and has called for international mediation to help reach a “fair and balanced” agreement.

The White House said earlier this month it supports talks to reach a sustainable agreement while “respecting each other’s Nile water equities.”
