Information is key for non-proliferation efforts. But the times when information was the exclusive purview of governments are over. Affordable, commercial and open-source monitoring capabilities empower states and societies alike, while challenging the ability of governments to preserve secrecy. Technological democratisation means that information is practically becoming a public good. And it allows for unprecedented transparency.

China is currently the main ballistic missile possessor and spacefaring nation which remains outside the Hague Code of Conduct against Ballistic Missile Proliferation (HCoC). This can be explained by China’s traditional opacity regarding its deployment of strategic missiles, but also its exports of ballistic systems or technologies abroad. This absence is nonetheless problematic for a regime based on voluntary transparency and confidence-building which aims at universality.

The issue of extending the scope of the Hague Code of Conduct to cruise missiles is regularly raised in academic and political discussions about the Code. Some non-subscribing States justify their refusal to join the instrument because of this exclusion, perceived as a major flaw. Indeed, cruise missiles have characteristics that can make them very effective in carrying weapons of mass destruction. It is therefore clearly of interest to consider extending the HCoC scope to these weapons.
