China has formally invoked its 2021 Blocking Statute for the first time, directly challenging recent US sanctions imposed on five Chinese refineries accused of participating in Iranian oil transactions [1]. According to MUFG’s Michael Wan, this move prohibits Chinese entities from complying with the US sanctions and signals a significant shift in the risk calculus for global market participants [1]. The statute is designed to alter the transmission mechanism of US secondary sanctions by warning third parties that compliance with US extra-territorial measures may now expose them to Chinese legal risks, rather than being the 'safe option' [1].
This development reflects China's growing resilience and efforts to diversify away from the US Dollar system, as well as its willingness to take more offensive measures to protect its interests [1]. The timing is notable, as it comes ahead of a planned summit between President Xi and Trump, suggesting that China may continue to escalate its pushback against US sanctions enforcement [1].
MUFG’s analysis highlights that this is a very significant development for global markets, as it increases legal uncertainty for third parties and could reshape how secondary sanctions are transmitted and enforced [1]. Market participants are advised to watch this situation closely, as further Chinese countermeasures may follow if this initial invocation proves effective [1].
CONCLUSION
China’s first formal use of its Blocking Statute marks a pivotal moment in the ongoing US-China sanctions dynamic, increasing legal risks for third parties and signaling a more assertive Chinese stance. Market participants should closely monitor further developments, as this move could reshape global compliance strategies and the enforcement of secondary sanctions.
