"I am ready to coordinate with my colleagues in the international community to mobilise financial supports if the region can offer a predictable and agreed path forward on the management of the river," Borrell wrote in a blog post.
He added that the European Union was invited as an observer to negotiations on the dam, chaired by South Africa.
"As the current chair of the African Union President Cyril Ramaphosa of South Africa has taken the lead to accelerating efforts to find a solution both for the short term issue of the filling of the GERD and for a longer term solution to this matter. In a few days, he will host a summit of the concerned leaders and I am very pleased that the European Union has been asked to serve as an observer to these talks," the blog post read.
Sudan and Egypt currently have tense relations with Ethiopia over disputes on the operation of Addis Ababa’s Grand Renaissance Dam, set to become Africa’s largest, but Cairo and Khartoum fear it would lead to water shortages.
Ethiopia has been pursuing the project since 2012. As of today, the dam’s construction has been completed by over 74 percent, according to local news outlets.
