NATO has called on Russia to co-operate on a joint missile defence system.
This comes a day after the US said it was abandoning plans to base missile and radar installations in Poland and the Czech Republic.
The move was warmly received by Russian Prime Minister Vladimir Putin.
NATO Secretary General Anders Fogh Rasmussen said the US, NATO and Russia should consider linking missile defence systems.
Studying how to tackle the proliferation of ballistic missile technology is in ‘NATO and Russia's fundamental strategic interest,’ he added.
‘We should explore the potential for linking the US, NATO and Russia missile defence systems at an appropriate time,’ he added.
In another development, Russia's envoy to NATO has said Moscow no longer saw the need to site its own missiles in the Russian enclave of Kaliningrad between Lithuania and Poland.
