you are referring to the RMB USD peg? Sure products would become more expensive and possibly some production will move to Vietnam, Bangladesh as already happens. But I claim China has reached such massive manufacturing scale that it will be hard for anyone else at this point to compete with China in regards to the inexpensive production of goods, not even if the RMB gains in strength.
Quote from Random.Capital:
It didn't. Germany is an incredibly powerful example of how a relatively small, well-educated and motivated country can not only survive, but thrive, when the national trade policy is rational.
Germany can compete with anyone. China has not demonstrated it can compete with anyone without a massive implicit US subsidy. Perhaps it can - but to date that has not been demonstrated.
