BEIJING (APP) - Chinese Premier Wen Jiabao while inviting more foreign companies to invest in his country, maintained Saturday that it is untrue to say that investment climate in China is worsening. China sticks to its opening-up policy, Wen added. In talks with heads of prestigious German and Chinese firms in northwest Chinas Xian city, Wen and visiting German Chancellor Angela Merkel aim to boost cooperation between the two nations. Currently, there is an allegation that Chinas investment environment is worsening. I think it is untrue, the state media quoted Premier Wen when answering a question from Juergen Hambrecht, chief executive of German chemical company BASF. Foreign firms have voiced concern Chinas indigenous innovation policy might provide incentives for government bodies to purchase products developed by Chinese companies. The World Bank in a July report gave China a low investment environment ranking. But the amount of foreign direct investment (FDI) that flowed into China in the first half of the year rose 19.6 percent year on year, according to data from the Ministry of Commerce (MOC). China attracted 12.51 billion U.S. dollars in FDI in June alone, up 39.6 percent year on year. Wen said, Foreign investment will not pour into a country where the investment environment is worsening. China, Wen said has relatively good infrastructure as well as fair and stable market environment. Wen said China welcomes companies which meet China industry policies to invest in China, adding that the government will ensure such companies having access to the Chinese market.
