Sudan's Democratic Unionist Party (DUP) said it is greatly concerned about the latest developments of the controversial Grand Ethiopian Renaissance Dam (GERD) file.

In a statement on Sunday, DUP noted that it closely follows up the negotiations among Egypt, Sudan, and Ethiopia, and all endeavors aimed at reaching a settlement that is satisfactory to all the parties concerned.

The Sudanese party expressed its regret over Ethiopia's unilateral move to fill and operate GERD without agreement with the Nile River downstream countries (Egypt and Sudan), lauding the Sudanese transitional government's conservative stance towards signing a partial agreement on the dam.

It warned that Sudan could be seriously affected if any harm happened to the dam after its operation.

It called on the transitional government to consult all parties and experts before taking any decision related to the dam.

DUP expressed its understanding of the Egyptian worries, calling on the Sudanese government to listen to the Egyptian vision.

It stressed its refusal of any bilateral agreement between Ethiopia and any downstream country.

Filling GERD without a tripartite agreement will make the three parties fight a losing battle, it added.

It called for the resumption of trilateral negotiations with a new positive spirit to resolve all the outstanding points and reach a just agreement achieving the interests of the three states
