BOLIVIAN TIN MINERS START HUNGER STRIKE About 9,000 miners employed by the state corporation Comibol went on hunger strike to press for higher wages, a miners union spokesman said. Victor Lopez, executive secretary of the miners union, told a news conference the strikers began to fast in the major tin mining districts of oruro and potosi and the action would spread tomorrow to la paz and other areas. The government has charged that the strike by the miners union, crippled by massive layoffs, is part of a left-wing destabilisation plan to coincide with the visit of West German president Richard von Weizsaecker, who arrives on a four-day official tour on Friday. But miners union chief Simon Reyes told reporters the strike had nothing to do with subversion and was to press for more government investment in Comibol. The government of president Victor Paz Estenssoro has streamlined the deficit-ridden state mining corporation laying off about 20,000 miners, two-thirds of the workforce, following a collapse of the international tin price in 1985.
