U.S. Economy still three times the size of China's

Since it is true that the U.S. economy is three times the size of China's it makes sense that the whole world is starting to feel better economically now that the U.S. is doing better now. For the past three years only China, India, Brazil and Saudi Arabia have been economically doing that well. If you add to this Canada you sort of get the picture worldwide. (And of course there are other exceptions that I didn't mention as well). So, now the U.S. is back on track (except in new jobs as in replacing the 8 million  jobs lost the last few years) the world is going to be progressively happier economically just from the spinoffs from an economy three times the size of China's. So, even China will  economically benefit from a financially stronger U.S.
