Prof. Xue was invited to present at the United Nations Economic and Social Commission for Asia and the Pacific (ESCAP) virtual expert group meeting on National Policy Framework for Cross-border Paperless Trade on 20 August 2020. The meeting identified the essential building blocks and attributes (legal and regulatory environments, both national and agency level) for the national policy framework; and helped to develop a template that could accommodate different models and varying degree of cross-border paperless trade measures developed at country level in the ambit of implementation of the Framework Agreement on Facilitation of Cross-border Paperless Trade in Asia and the Pacific. In the presentation, Prof. Xue emphasized the importance of studies on the cross-border data flow and the mutual recognition criteria of CB paperless in domestic laws. In the written comments, Prof. Xue also pointed out the inappropriate omission of the Chinese E-Commerce Law entirely in the country study on Chinese paperless laws and regulations as well as the legal mistakes on implementation of the e-port system.
