CHINA'S HEILONGJIANG PROVINCE BOOSTS GOLD OUTPUT Gold output in the northeast China province of Heilongjiang rose 22.7 pct in 1986 from 1985's level, the New China News Agency said. It gave no figures. It said the province, China's second largest gold producer after Shandong, plans to double gold output by 1990 from the 1986 level. China does not publish gold production figures. However, industry sources estimate output at about 65 tonnes a year, with exports put between 11 and 31 tonnes. China is selling more gold abroad to offset large trade deficits in recent years, western diplomats said.
