European firms claim that an uneven playing field in China costs them US$22.8 billion in lost revenue annually, according to a survey from the European Union Chamber of Commerce, The Financial Times reported. The chamber’s report also showed that only 29% of European firms operating in China are optimistic about profitability due to the slowing economy and rising costs. This report comes as China and the EU prepare for a possible trade war – which more than half of EU member states oppose – over tariffs on Chinese solar panels and telecommunications equipment. Trade between the EU and China is estimated to be valued at US$1.3 billion (RMB8 billion) per day.
