Europe still has significant headwinds, Canada and the middle east...that's pretty obvious with $30/barrel oil prices, Russia of course not doing terribly great, capital flooding back to the US from Central and South America due to interest rates rising.
Keep in mind, a lot of manufacturing is moving back to the US from China with automation being cheeper than (quickly rising) Chinese labor rates [1] [2] [3].
If China cannot stoke internal demand quickly enough (and I assure you, it cannot), it's going to slide into a deep recession. On the bright side, this is going to help cool off London, Toronto, Vancouver, SF/LA, Miami, and central Texas property markets (where a lot of Chinese money was flowing into).
