Export controls: America’s other national security threat

Chad P. Bown (PIIE)

Working Papers 20-8


While the public was transfixed by the Trump administration’s policies alleging that imports were a threat to America’s national security during 2017–20, there was a concomitant and more quiet US policy shift on the export side. Addressing the national security threat presented by exports posed different economic and institutional challenges from those associated with import policy, including the acknowledgment that export controls for legitimate national security reasons can be the first-best policy to confront the problem at its source. Yet, export controls could also be misused as a beggar-thy-neighbor policy to redistribute economic well-being across countries, even from one ally to another.

This paper describes how US export control policy evolved over 2017–20, as well as the international institutions—first the Coordinating Committee for Multilateral Export Controls (COCOM), then the Wassenaar Arrangement—historically tasked with multilateralizing US export restrictions used to protect national security. With the potential for US export control policy to brush up more frequently against WTO rules designed to limit the use of export restrictions, the paper also highlights new challenges for the WTO’s system of resolving trade disputes. Overall, a US failure to strike the right balance for its export control policy would result in it being ineffective at addressing national security risks, costly for the economy, and problematic for trade and diplomatic relations.
