Existing research has provided ample evidence that in globalized markets, regulatory policies introduced by influential states often diffuse to other jurisdictions and stoke policy change beyond their own borders. In his article “Victims of their own success abroad? Why the withdrawal of US transparency rules is hindered by diffusion to the EU and Canada” published in the Journal of European Public Policy, Bjorn Kleizen argues that the diffusion of regulatory rules can come back to bite legislators seeking to change them in their original jurisdiction. Bjorn provides an in-depth case study of the Trump administration’s decision to withdraw payment transparency regulations for extractive industries, which had been introduced by the previous U.S. administration. He shows that the EU and Canada’s decision to emulate Obama-era practices meant that U.S. oil, gas and mineral multinationals were still faced with disclosure rules pursuant to EU and Canadian law, undermining the effectiveness of U.S. lawmakers’ attempts to reduce the regulatory burdens. Bjorn’s argument suggests that when “states co-operate to create rules that are applicable to each other’s companies, the layering of these various rules may create a difficult-to-remove multilateral framework.”
