There is a widespread consensus that China needs to rebalance its export‐driven growth paradigm towards a more consumption‐based one and that such process is to be accompanied by the transition towards the renminbi's full convertibility. However, the Chinese authorities have so far acted with great caution because this transition cannot but accelerate the slowdown of China's growth which will likely occur because of other structural factors. We address these issues by means of a two‐country two‐stage (before and after the renminbi's full convertibility) model, which reproduces some qualitative features of China's growth pattern and its relationship with the United States. We analyse the extent to which altering the Chinese exchange rate regime, as well as other policies affecting sensitive social and economic issues, may impact on the short‐, medium‐ and long‐term evolution of the Chinese economy. The paper shows that by lifting the controls on the capital account and letting the currency float, the Chinese authorities will renounce those policy instruments for controlling the allocation of the national resources and the dynamics of China's economy.
