The head of the European Union Chamber of Commerce in China (EUCCC) said the business group was concerned about growing protectionism in China, and urged China to open its market, Dow Jones reported. Joerg Wuttke, president of the EUCCC, made the comments while releasing the chamber’s annual position paper. "Over the past year, the European Chamber has noted a gradual slowdown – and in some cases a partial reversal – in the economic opening up process. We are convinced that this is an ideal moment for China to adopt a new and bolder cycle of reforms," he said. Wuttke said China lacked a "clear checklist" for reform, but added that government efforts to reduce overcapacity were encouraging. He also highlighted the recent detention of Rio Tinto executives in the company as an area of concern for foreign companies operating in China. "The definition of national interests is totally hazy," making it difficult for foreign companies to ensure compliance with Chinese law, he said.
