9. UUIE SUPPORTS ECONOMIC RAPPROCHEMENT

KYIV. The Ukrainian Union of Industrials and Entrepreneurs made two important statements March 11. Although the first one strongly criticized the policies of government ministries and NBU, the second supported the economic cooperation treaty signed with Russia last month. The first criticized high yield T-bills for distracting domestic investments for purely speculative purposes. The 44% discount rate squeezed businessmen by depriving them of credit resources.
