This chapter delves into the question of the impact of extraterritorial and secondary sanctions on private contractual relations. It opens with a discussion of the characterisation of extraterritorial and secondary sanctions as potential legal or factual impediments to the performance of contractual obligations. A detailed analysis of the case law follows, bringing to the fore some degree of reluctance on the part of judicial authorities to allow operators to suspend the performance of their contractual obligations or to terminate contractual relations on account of their exposure to extraterritorial or secondary sanctions, at least in the absence of sanctions or force majeure contractual clauses. The chapter also explores the potential tension between such sanctions, on the one hand, and measures – commonly referred to as blocking statutes – enacted by states or by the EU to thwart their effects, on the other hand. A discussion, in this respect, of the relevant case law reveals a quest for a balance between policy objectives and economic soundness and shows the existence of incongruent views on the compatibility of sanctions clauses with blocking statutes.

Sanctions are intrinsically complex. Implementation of sanctions regulations often entails navigating an extremely dynamic environment consisting of numerous restrictions and prohibitions, difficulties in interpretation, inconsistent measures adopted by imposing jurisdictions and countermeasures. This has been evident following the sanctions against Russia, often described as unprecedented in scale. The more frequent resort to sanctions further means that an increasing number of international contractual relationships are affected. Financial institutions operating globally are particularly impacted. This is exacerbated by the use of secondary sanctions which remain a controversial foreign policy tool and even subject to countermeasures, for example, blocking statutes. Consequently, financial institutions and other economic operators with an international presence, torn between two conflicting regimes, face an unsolvable legal dilemma. This uncertainty extends to the termination of contracts involving persons or activities subject to secondary sanctions. Although in most cases international (financial) contracts contain sanctions clauses (often under force majeure provisions), it remains unclear whether these can be relied on, especially where the institution’s own jurisdiction opposes secondary sanctions. This chapter presents in more detail what are the practical challenges in sanctions implementation. It focuses on financial institutions and provide recommendations on how such challenges could be addressed.

This chapter explores the extraterritorial application of the U.S. sanctions: namely, the ability of those sanctions regulations to reach non-U.S. actors or activities taking place outside of the United States. The chapter examines a recent trend towards increasing extraterritorial enforcement by the U.S. sanctions authority. In particular, the chapter discusses the objections of China to such extraterritorial application of U.S. sanctions laws. Of particular focus are Russia’s and China’s attempts to de-dollarize and resort to alternative financial networks to lessen the impact of these sanctions.
