The promise of China's G20 presidency

Specifically, the AIIB will (among other things) provide funding for China's ambitious Belt and Road Initiative, which aims to enhance trade linkages throughout Asia, across the Middle East, and into Europe, through massive infrastructure investment. The fact that more than 50 countries signed on as founding members indicates that members' interest in securing resources to meet urgent infrastructure trumps geopolitical competition.

The same brand of pragmatism was apparent in China's response to its exclusion from the recently agreed Trans-Pacific Partnership (TPP) trade agreement, spearheaded by the US and including 12 Pacific Rim countries. Instead of grandstanding, China has shown its willingness to pursue different types of trade arrangements, as needed. If China can grasp the opportunity of the G20 presidency to broker a deal to conclude the World Trade Organization's long-stalled Doha Development Round, its credentials as a global stakeholder would be enhanced.

There is more promising news. The Chinese renminbi has joined the US dollar, the British pound, the euro, and the Japanese yen in the basket of currencies that determines the value of the International Monetary Fund's reserve asset, special drawing rights. With the renminbi moving one step closer to becoming a reserve currency, China's capacity to help the world - and especially emerging-market economies - cope with impending market volatility will be greatly enhanced.

Building a robust, unified, and fast-growing global economy will be extremely difficult even under the most favorable circumstances. It will be impossible if large swaths of the world - most notably, the Middle East - remain mired in chaos and violence. Given this, China could, like Turkey, use its G20 presidency to promote consensus on the need to end the Syrian conflict and to support long-term peace and economic development throughout the Middle East by pursuing strategies that revive trade, investment, and employment.

Next year, the G20 has an important opportunity to show that it can deal effectively with global crises, from the risk of secular stagnation to the scourge of transnational terrorism. With the right mix of realism and power sharing, China's G20 presidency could catalyze important progress - and perhaps even place a firm foundation beneath a new global economic architecture fit for the twenty-first century.
