China warns on U.S. soy as Chinese goods under scrutiny | Reuters:

"BEIJING (Reuters) - China, the world's top soy importer, has accused the United States of exporting substandard soybeans even as its own exports come under growing scrutiny abroad over safety concerns.

'Recently, supervision bodies have found numerous quality problems in soybeans imported from the United States,' the General Administration of Quality Supervision, Inspection and Quarantine said on its Web site (www.aqsiq.gov.cn) on Wednesday.

Harmful weeds and contaminated dirt had been found among the beans, which could threaten China's agricultural and forestry production and ecological safety, the quality watchdog said."

Tit for tat, as the Chinese scramble to recover their global image.
