In 9 years of its history，the G20 has formed a unique work mechanism and a number of stable priority issues. In the background of sluggish global economic growth and complex global economic performance，there is a high expectation for the Hangzhou Summit. For the first time，China，as the 11th G20 summit presidency，has designed the G20’s agenda and navigated the global economic governance in 2016. China’s presidency not only reflects G20’s existing experience and succession，but also shows Chinese unique wisdom in the field of economic governance. The successful G20 Hangzhou summit has left a fruitful and historical mark for the G20 and global economic governance.
