China faces multiple challenges
1) Slowdown in Europe and USA means that their exports are sputtering and manufacturing has already started contracting
2) Protests in cities and villages grows against rampant corruption and land grabbing by Communist officies.Lack of democracy means violent protests at times.
3) Debt is becoming a huge problem with local government vehicles facing trouble as they can no longer raise money from real estate sales which has fallen by 20-25%
4) Massive industrial overcapacity is being exported outside.This has made the other trading nations put duties and curbs.A big trade war with USA cannot be ruled out.Chinese solar and wind products faced countervailing duties and dumping charges.China has already imposed high duties on US car imports.
