Since the Group of Twenty (G20) was founded in 1999, the United States and China have generally managed to restore or instill confidence in the international order, even when other members were mired in crisis. And in the ensuing years, both countries have maintained stable growth and weathered economic storms better than most. G20 summits thus became occasions for the US and China to flex their muscles as they helped others, not least the members of the eurozone. But, at this year’s G20 summit in Hamburg, Germany, the tables seem to have turned. The US under President Donald Trump has no appetite – or, it appears, the ability – for global leadership, and China is confronting mounting threats to growth and stability, whereas the European Union is now growing faster than at any time since 2008. And recent elections in the Netherlands, the United Kingdom, and France seem to have closed the door on the threat of populism in Europe, at least for now.
