The ASEAN+6 Single Window (ASW+6) in this study refers to the geographic expansion of the ASEAN Single Window (ASW) to enable cross-border electronic exchange of trade-related data and documents among ASEAN member states and six FTA partners, namely, Australia, China, India, Japan, New Zealand and South Korea. The ASW is part of ASEAN’s trade facilitation reform to reduce intraregional trade costs and time.

This study considers cross-border paperless trade measures to represent the implementation of ASW+6, using data from the UN Global Survey on Digital and Sustainable Trade Facilitation in 2019. The simulation analyses reveal that the ASW+6 has significant potential to reduce times required to export and import, and to boost trade in ASEAN and its FTA partners.
