Trumpism may now become the new populist world order of economic governance. Populist support contributes to Trump's 2016 presidential election victory and his key embrace of trade protectionism and accommodative fiscal stimulus. Trumpism echoes Carl Schmitt's fundamental critique of modern liberalism. This core critique reflects disdain for the universal aspirations such as absolute individual liberty and economic freedom.

Liberals place individual rights at the core of their political communities. In principle, these rights extend to every citizen, so absolute American liberty can be a decent idea. However, this liberal school of thought makes U.S. states vulnerable to the aggressive demand by domestic private interest groups and foreign nations. This latter retort reflects the key centerpiece of Trump's presidential election campaign.

As dominant market players such as China and Russia refuse to play by the rules of liberal economic governance, the Trump administration has to engage these players in a wider G20 circle.

China's recent economic rise suggests that the millennium world order of economic governance should be more inclusive. As Trump suggests at the G7 world summit, Russia should also be part of this new populist world order. Another addition can be India that represents a 1.3 billion population-dividend-equivalent to China. For this reason, Jim O'Neill, former chief economist at Goldman Sachs, advocates the fresh insight that we should broaden the practical scope of the G7 summit. Instead, a G10 summit or even a G20 summit must encompass all major market economies.

This inclusive approach emphasizes the new populist world order on key economic issues from global capital control and credit supply expansion to climate change and environmental degradation.
