high inflation, higher int.rate by central govt to make borrowing more expensive; less investing less inflation pressure
higher int.rate also means higher return for RMB backed assets
therefore more foreign investing into China; more demand for RMB
RMB appreciation
To conclude, high inflation usually leads to appreciation of the home currency
and China's CPI doesn't look good, which is probably why Chinese govt very reluctant to raise currency value to add additional pressure
I maybe wrong.. please correct me if that's the case. Thank you
