Egypt's Mission to the United Nations (UN) in Geneva held a webinar on Thursday with legal experts and hydrologists to highlight Egyptian efforts to reach a mutually beneficial agreement on the Grand Ethiopian Renaissance Dam (GERD), foreign ministry spokesman Ahmed Hafez said on Twitter.

The Egyptian negotiating delegation also participated in the webinar, Hafez said.

Egypt, Sudan and Ethiopia concluded their most recent round of talks on the megadam in August, without reaching an integrated draft agreement on the filling and operation of the hydropower project.

Addressing the 75th Session of the UN General Assembly, President Abdel-Fattah El-Sisi said on Wednesday that the Nile "is not restricted to a party and its waters are considered a matter of survival for Egyptians, without infringing our brothers’ rights."

"We've spent almost a decade in painstaking negotiations with our brothers in Sudan and Ethiopia, in an endeavour to reach an agreement regulating the filling and operation of the dam and strike the required balance between achieving the development requirements of the friendly Ethiopian people and safeguarding Egypt's water interests and ensuring its right to life," El-Sisi said, adding that these efforts, however, did not yield the desired results.

The president stressed that the GERD negotiation period "should not be extended indefinitely" in order to impose a status quo.

Ethiopia began construction on the dam in 2011 and completed the first filling of its reservoir this summer, despite not having reached an agreement with its downstream neighbours.
