Breaking News-RTRS-China quarantine warns on US soybean import quality

BEIJING, Dec 23 (Reuters) - China's quarantine bureau has warned the United States over the quality of imported soybeans after finding traces of harmful pesticides in one U.S. soy cargo, the bureau said in a statement on Tuesday.
The warning comes as China's government faces calls for import curbs because state purchases have pushed up prices and cheap imports have flooded the domestic market.
