Concerns about the harm caused upon orbiting space objects – whether intentional or accidental – have increased in recent years, as well as the emerging awareness that the security and safety of national satellites – of vital importance for modern societies but at the same time so vulnerable – relies on a collective effort. In December 2008 the EU responded to these concerns by adopting a Draft Code of Conduct (EU Draft CoC) for outer space activities.

The Hague Code of Conduct against Ballistic Missile Proliferation, the Missile Technology Control Regime and United Nations Security Council Resolution 1540 each contribute to the international regime for the nonproliferation of ballistic missiles. The three instruments aim at controlling both horizontal and vertical proliferation.
