What does currency realignment mean? Once a major currency realigns, it will attract a lot of dissension from other trading partners competing in the same grouping.

The two main partners to complain would be the US and EU, especially at the top of the production and manufacturing chain. Autos and electrical products manufacturers are the most directly affected.
