Special Economic Zones (SEZ) have become the forefront in China to test legal and technological reforms for digital trade. This chapter explores three cutting-edge case studies in China’s SEZs: the Beijing blockchain-based Single Window deposit box; newly established big data exchanges in Beijing, Tianjin, and Shanghai SEZs; and pilot projects in financial, medical care and automobile industries to flow data across the border in the Shanghai SEZ. It scrutinizes China's experiments in the context of its applications to join the Comprehensive and Progressive Trans-Pacific Partnership and the Digital Economy Partnership Agreement. It argues that the development of Chinese domestic law for digital trade is shifting away from the traditional paradigm that uses international commitments to push domestic reform or make domestic law according to international law. The development of Chinese domestic law for digital trade relies much more on China’s domestic needs than what FTAs negotiations require. FTAs are increasingly becoming a tool for China to shape international law rather than a benchmark for legislating domestic Chinese law.
