That is how I have always seen it. They are only 300 million people, thats not a whole lot in consumption needs. They will find that making in America is costly, the public will pay for that with their wallets. Importing will be costly as the US will be a low favoured market, given that us other countries will be tariffed or lose exports to the US. The globe will find a way, to produce goods without US involvement, and to export without US involvement. Its happening now. Ford pulled out of a 1.6 billion deal with Mexico, Mexico is seeking trade partnerships elsewhere, its all happening.
Long term the world will be better off as the US will have less pull. Us other countries will be sorted out, amongst ourselves. China will dominate finance and trade, India will get a nice boost and be more involved in world trade. 2nd world countries probably ride the wave. A bit to like actually. Time to rejuvenate world trade and with that, relations.
Our future lays with China, let the US do what ever they do and we should get on with building prosperity with Beijing.
Our future lies with trade regardless of Country...whilst China is valuable as a partner they are not reliable and NZ cannot afford to have all its eggs in the one basket. Most trade is still completed in US dollars.
