Starting points

It all depends where you start from.  This is the chart from my piece on the KMIT economies (that's Korea, Mexico, Indonesia and Turkey)  Looking at the topmost chart, it does seems as if the KMIT economies are growing more slowly than the BRIC (Brazil, Russia, India and China)  But choose a different base period (same weights; lower chart) and that's not nearly so evident.  A bit slower recently perhaps, and they declined much more during the GFC than the BRIC countries, as you'd expect given that they're much smaller and more dependent on global trends. Large continental economies are much less tied to the global cycle.  In fact they set it.
