This Sunday, Chinese President Xi Jinping will kick off the 2016 G20 Summit in the rich eastern city of Hangzhou. The first summit of this kind to ever take place in China comes at a testing time for the global economy. World leaders are called to address enduring challenges, such as a downward trend in global growth, escalating trade protectionism, and renewed risks of currency wars. At the same time, the summit will be a chance for China to show its commitment to rebalancing the domestic economy while fostering international economic development and stability. While it remains to be seen whether G20 leaders will be willing to move beyond symbolic steps, the Summit will certainly be a litmus test for governments to show that the G20 is still relevant and able to deliver.
