US retailer Wal-Mart Stores (WMT.NYSE) stated on Wednesday that it will upgrade its vendor compliance process in China after state-owned China Central Television (CCTV) criticized the firm for circumventing its quality control process and fast-tracking certain products with higher profit margins, Reuters reported. The statement said it will “ensure the correct documents and other required items are in place before the products are sold in our stores.” Wal-Mart is the latest in a series of foreign companies CCTV has taken to task on issues ranging from pricing to low quality products and poor customer service.
