most likely this is posturing, at least in part. One key difference between Chinese and Western culture is the degree to which "a deal can be renegotiated". T

most likely this is posturing, at least in part. One key difference between Chinese and Western culture is the degree to which "a deal can be renegotiated". The Chinese tend more towards "a deal is always open to renegotiation". Western minds tend to try to live with and work around the ink that's already dry. btw, I have no idea what WTO agreements are in place on these issues. There may be little details that hold China to being required to export these materials.
