China decided not to appeal a WTO ruling that Beijing unfairly blocked US credit card companies including Mastercard (MA.NYSE) and Visa (V.NYSE) from its market to protect state-owned China UnionPay, Reuters reported. Beijing now has 30 days to outline the measures it will take to comply with the July 16 WTO ruling, potentially opening up the lucrative mainland market where more than US$1 trillion in electronic payment card transactions are processed each year. In a statement on Friday, US Trade Representative Ron Kirk welcomed China’s decision not to appeal the ruling and said as many as 6,000 jobs could be created from increased access to China’s electronic payments market. According to a separate report, German Chancellor Angela Merkel told Chinese officials on Friday that Germany did not want to start a trade war with Beijing over solar exports to Europe, but that Beijing would need to make concessions if it wanted to prevent EU action.
