On June 2020, Duncan Smith launched the Inter-Parliamentary Alliance on China, becoming the co-chair of the alliance in the UK with Labour peer, Helena Kennedy. The alliance seeks to, "promote a coordinated response between democratic states to challenges posed by the present conduct and future ambitions of the People’s Republic of China. By developing a common set of principles and frameworks that transcend domestic party divisions and international borders, our democracies will be able to keep the rules-based and human rights systems true to their founding purposes." In a launch message, Duncan Smith explained, "This challenge will outlast governments and administrations and it transcends party politics."
