Beijing and Berlin can infuse fresh blood into G20

As global leaders prepare to gather in picturesque Hangzhou in East China's Zhejiang province to attend this year's G20 Leaders' Summit, and the German port city of Hamburg prepares to play host to the next G20 summit, they can learn a great deal from a rapidly growing economy and an industrialized giant about how to improve their respective economies.

But to lead the world economy out of the ongoing downturn, world leaders have to think "beyond G20", which means they have to focus on more than macroeconomic policy coordination and make earnest efforts to reform the global financial regime. For example, they should seek to improve the livelihoods of people across the world and increase their respective countries' competitiveness.

The mission of the G20 summit is to inject new life into the global economy, something which China and Germany, as G20 summit hosts in 2016 and 2017, can review to improve their own competitiveness.
