Reconciling open science with technological sovereignty

In history, open science has been effective in facilitating knowledge sharing and promoting and diffusing innovations. However, as a result of geopolitical tensions, technological sovereignty has recently been increasingly emphasized in various countries' science and technology policy making, posing a challenge to open science policy. In this paper, we argue that the European Union significantly benefits from and contributes to open science and should continue to support it. Similarly, China embraced foreign technologies and engaged in open science as its economy developed rapidly in the last 40 years. Today both economies could learn from each other in finding the right balance between open science and technological sovereignty particularly given the very different policy experience and the urgency of implementing new technologies addressing the grand challenges such as climate change faced by mankind.
