China has continuously recorded power gains over the entire period from 2005 to 2017, but the Power Shift Rate (PSR) has slowly been declining since 2013. From 2015 to 2017, China’s Power Score has risen from 12.3 to 12.75, an increase of 0.45 percentage points, which means that its power growth has decelerated compared to the PSR of 0.95 in the period of 2013/15. This development reveals that China's catching-up to the United States has slowed down since 2013, although it continues to progress.
