U.S. Treasury Secretary Paul O'Neill does not plan to put indirect pressure on the European Central Bank to lower interest rates further when he meets with finance ministers from Europe and other industrial nations in Rome Saturday, a senior Treasury official said Tuesday. The senior official acknowledged there may be "differences of opinion" with the Europeans, but said O'Neill does not plan to advise them on monetary policy. The ECB will not be directly represented at the finance ministers portion of the annual Economic Summit, which does not include central bankers the way regular G-7 meetings do. The senior official praised Japan's economic and financial reform plans and said he does not expect them to have "severe" short-term repercussions. On the contrary, he said he expects there to be some "offsetting positive effects."
