The American regulators have heard those stories before. In July, the chairman of the China Securities Regulatory Commission, Guo Shuqing, told Mary L. Schapiro, then the chairwoman of the United States Securities and Exchange Commission, that he thought an agreement could be reached. It turned out that the Chinese insisted they would provide documents only if the S.E.C. promised not to use them in an enforcement proceeding without Chinese permission.

wow, it sounds so much like the Forestry Bureaus, who have written the confirmations for Sino-Forest's timber assets, and insisted that the confirmations can not be used publicly as ownership certificates. Why? Why should the Chinese Government officials always do things like that?
