Most frequently, Oliver advises on EU and UN sanctions regimes, and their relationship with US and UK sanctions frameworks. He recently edited a chapter on economic sanctions for an OUP book published in Spring 2023. Oliver was also a co-author on an article for the New York State Bar Association titled: ‘Sanctions: Foreign Policy, Economic Warfare, or Both?’.
