China's top quality-control official has made public a list of defects and dangers found in US products, the Wall Street Journal reported. Li Changjiang, head of the General Administration for Quality, Supervision, Inspection and Quarantine, or Aqsiq, presented the list to the newspaper with a list of about a dozen American exports that have been held for quality problems in the past year. These included products from General Electric, Philips Electronics and Deere & Co. Li said that 4,845 shipments, or nearly 2% of the total number of shipments exported from the US to China between January and July, had quality problems. Li said American importers and Chinese export companies should be held responsible. The list comes after a summer of recalls of millions of China-made products by American companies such as Mattel.
