Asia’s businesses and households rely on a global system of rules and institutions to do business overseas. That global system is under attack, and Asian governments are yet to mobilise to stop it. Governments in the region weaken the system every time they preference short-term bilateral band-aids over long-term multilateral solutions; from managing US–China tensions to the response to COVID-19. Now is the time for Asian governments to show leadership on the global system and its reform. If they don’t use it, they’ll lose it.
