A group of Egyptian expats in the US organised a demonstration in front of the White House on Sunday to support Egypt in regard to the Grand Ethiopian Renaissance Dam talks.
The group held banners demanding support and respect for Egypt's rights to the Nile water.
Egyptian expats have also launched a petition on change.org to collect signatures in support of Egypt’s position.
Egypt initialled an agreement on the mega-dam’s filling and operation in February, which was the result of several rounds of trilateral talks between Egypt, Ethiopia and Sudan that were moderated by the US and the World Bank.
Ethiopia withdrew from the last round of talks, while Sudan also did not sign the agreement.
Ethiopia has accused the US of favouring Egypt in the row over the dam, which Cairo fears will significantly diminish its water supply from the Nile.
Egypt, meanwhile, believes that Ethiopia is intentionally hindering the course of the talks.
The dam is now more than 70 percent complete, and Ethiopia plans to start filling its reservoir in July.
