Private International Law as Foreign Relations Law? Orienting Chinese Private International Law Towards Sustainable Development

The Chinese Foreign Relations Law (‘the FRL’) – a collection of rules legalizing China's foreign policies – was enacted in 2023. While technically a set of policy goals and public law rules, it provides an opportunity to orient Chinese private international law (‘PIL’) towards sustainable development. Notably, the FRL connects Chinese PIL with sustainable development for the first time and revisits the conceptions of what is being understood as ‘domestic’ versus ‘foreign’, and ‘public’ versus ‘private’. This article explores how PIL can leverage this shift to accommodate sustainability as a normative value, foster positive interactions with foreign laws and courts, and develop a robust and tailored regulatory function. By doing so, Chinese PIL, as a form of foreign relations law, can expand its function beyond conflict resolution and develop a role in China's foreign policy and global sustainability governance.
