To qualify as the next manufacturing hub of the world, that nation would need to have below list:-
1. Adequate power supply (power plants, power grids)
2. good transportations (sea ports, air ports, highways),
3. good communication systems (telephone lines, internets access)
4. Large supply of cheap, educated, hardworking and skilled workers
5. Good matrix of supply and service chains (raw materials suppliers, parts suppliers, finance & banking, management services etc. etc.)
6. Good vocational educations
7. Taxation systems friendly to manufacturing, import and export companies.
8. Political stabilities.
So which of your countries can fit the bill? India, Indonesia, Mexico?
IMO, China will still be the top in next decade or two, but the next manufacturing hub will not be a single country but a region consist of several countries each will do what they do best in certain products.
