"We hold that economic aid to the developing countries must strictly respect the sovereignty of the recipient countries and must not be accompanied by any political or military conditions and the extortion of any special privileges or excessive profits. Loans to the developing countries should be interest-free or low-interest and allow for delayed repayment of capital and interest, or even reduction and cancellation of debts in case of necessity. We are opposed to the exploitation of developing countries by usury or blackmail in the name of aid."
January 1, 1970
