JAPAN MINISTER SAYS ABOUT 170 YEN APPROPRIATE
  International Trade and Industry Minister
  Hajime Tamura told a parliamentary session Japan's small- and
  medium-sized enterprises are seriously suffering from the yen's
  rise and can only stand levels around 170 yen.
      He also said he still believes a dollar exchange rate level
  plus or minus 10 yen from 170 yen would be within levels agreed
  upon last month in Paris by six major industrial nations.
  Finance ministers of Britain, Canada, France, Japan, the U.S.
  And West Germany agreed on February 22 to cooperate in
  stabilizing exchange rates around the current levels. The
  dollar had closed here at 153.77 yen on February 20.
