Since 2008, G20 leaders have repeatedly committed themselves not to resort to protectionism and to conclude WTO negotiations expeditiously. The jury is out on the extent to which they have lived up to the first promise; they have failed to deliver the second. Anemic global trade growth rates since 2010 imply that trade has not been a driver of much-needed economic dynamism. This paper argues that the G20 should pursue a more ambitious trade agenda and that there is much that greater leadership by the G20 could do to reinvigorate the trading system. A first step would be to commit to concrete actions that can be implemented by individual governments on a concerted basis and that center on reducing trade costs and improving access to services for firms. The Chinese presidency should also seek to have the G20 commit to more effective monitoring and analysis of trade policy broadly defined (including subsidies and investment incentives) and the impact of the many preferential trade agreements involving China, the EU and the USA, the world's largest trading powers.

振兴全球贸易体系：二十国集团能做什么？

自2008年以来，二十国集团（G20）领导人一再承诺不诉诸保护主义，并迅速结束WTO谈判。陪审团对他们能否兑现第一个诺言的程度表示怀疑。他们没有交付第二个。自2010年以来，全球贸易增长率呈负增长趋势，这表明贸易并没有推动急需的经济活力。本文认为，二十国集团应追求更雄心勃勃的贸易议程，而二十国集团的更大领导层可以重振贸易体系。第一步将是采取具体行动，由各国政府共同采取行动，其重点是降低贸易成本和改善企业获得服务的机会。
