Three months ago the International Monetary Fund (IMF) said it had adopted a new set of lending guidelines that would permit borrowing countries to take control of their economies like never before. But over the past week, the Fund flexed its muscles over two of the world's poorest countries and imposed conditions that critics predict will be disastrous for the poor in those nations -- and that signified business as usual for the Washington-based institution. The IMF told Zambia -- an African country ravaged by debt, mismanagement, and disease -- that it will delay one billion dollars in debt relief until the poor nation sells its state-owned commercial bank, the Zambia National Commercial Bank.
