After years of continuously rising of Renminbi, China has become more and more willingly to let Renminbi depreciate moderately and increase the flexibility of RMB exchange rate at the same time.

Correspondingly, Chinese domestic easy monetary should have RMB exchange rate stability as its precondition and try to avoid participating in the process of "competitive devaluation".

The best method is giving decision-making rights back to the market.
