By 2000, the number of nature reserves increased to 1,276, while at the same time, the total area protected in nature reserves was up to 123 million ha. Of the total number of reserves, 908 sites ...展开更多

When accumulated foreign exchange reserves surpass a sufficient and an appropriate level, the costs, risks and impacts of holding reserves on the macroeconomy of a country need to be considered. The Chinese Government established China Investment Corporation （ CIC） in 2007 to diversify its investment of foreign reserves and to raise investment income. However, because of certain conflicts of interest and institution-design caveats, CIC possesses some internal weakness, including a vague orientation, mixed investment strategies and an inefficient bureaucratic style. Although the subprime crisis has softened certain regulations and lessened rejection by the USA of ClC potential investments, the increased volatility and uncertainty of the market means that CIC is facing some new challenges in terms of its investment decisions. Moreover, CIC is competing with other Chinese investment institutions for injections of funds from the Chinese Government.展开更多
