CAIRO (Reuters) - Egypt said on Saturday it was highly concerned that Ethiopia had not responded to an invitation to discuss a dispute over a giant dam that Ethiopia plans to build on the river Nile.
"Egypt is deeply worried that Ethiopia has not yet reacted to the invitation Egypt's minister of water and irrigation made to conduct a meeting in Cairo on the consequences of the dam," a statement issued by the foreign ministry said.
Egypt fears the dam will reduce water flows vital for its 84 million people.
Recently ousted Egyptian President Mohamed Mursi said last month that "all options" were open in dealing with the issue, prompting Ethiopia to say it was ready to defend its $4.7 billion dam, set to be built near its border with Sudan.
The foreign ministry statement, issued just days after an interim cabinet was sworn into office in Cairo, shows the dam issue is a major priority for the new government.
Ethiopia summoned the Egyptian ambassador last month after politicians in Cairo were shown on television suggesting military action or supporting Ethiopian rebels.
Egypt also last month hosted an experts' meeting to study the impact of the dam on Egypt and Sudan, the two downstream Nile states. The foreign ministry said Cairo's proposed meeting was going to discuss that study, but gave no further details.
Egypt, whose population of 84 million uses almost all of the Nile water available to it, cites a 1929 pact which entitled Cairo to 55.5 billion cubic meters a year of the Nile's flow of around 84 billion cubic meters.
Ethiopia and five other upstream Nile states, such as Kenya and Uganda, say Egypt's claims are outdated and have signed a deal effectively stripping Cairo of its veto based on colonial-era treaties over dam projects on the river.
