Vietnam’s anti-China riots this past May have helped American businesses in big ways. Vietnam is a member of ASEAN and will be a member of the Trans-Pacific Partnership instead of China (both America friendly trade blocs). In addition, Vietnam wants American investment, the government has made clear that it values the Americans here and wants their businesses to stay.
As many foreign businesses try to reduce costs or over-dependence on Chinese manufacturers, they will look to go abroad—Vietnam in particular. Vietnam provides low wages and high quality manufacturing—two of which China is currently lacking.
