Angelo has led efforts to try to mobilise more than US$80 million from international donors and aid agencies, which is critically needed to avert an unprecedented humanitarian and food crisis in Zimbabwe.

But the donors are said to have told Angelo that unless Harare moves to implement a sound exchange rate policy, among other key demands, then no significant food aid will be given to Zimbabwe.

Angelo, who retuned to Zimbabwe earlier this week, refused to discuss his trip to New York or the fresh demands by the donors when contacted by this newspaper.

Finance Minister Simba Makoni was this week quoted by the state-controlled Herald newspaper as having told Parliament that the government did not have any plans to devalue the dollar.

As well as implementing a sound exchange rate, donors are demanding that the government takes measures to reassure the international community that property rights are upheld in Zimbabwe.

The protection of these rights, the donors said, was a prerequisite if Zimbabwe was to lure back foreign capital and investors.
