Despite the five significant international treaties laying the foundations of the legal framework in the space era, regulatory gaps have begun to surface, especially in light of the latest developments characterised by a surge in satellite usage and commercial activities. At this second edition of our Space Law webinar series moderated by Dr Anthony Neoh, Professor Zhao Yun reviewed the issues of space commercialisation and privatisation and the ensuing challenges such as space security and sustainability, moving on to a detailed examination of an array of soft-law rules and international cooperation projects as important means of promoting mutual benefits, sharing of common resources, peaceful use and long-term sustainability of outer space. This webinar attracted a diverse group of registrants comprised of academics, engineers, legal professionals, business executives, representatives from governments and consulates, etc. coming from 32 countries/regions around the world.
