Nato defence and foreign ministers are meeting today at Nato headquarters in Brussels, Belgium, to draft and reshape the alliance's vision against cyber and missile threats for the next decade.
The 11-page mission statement, drafted by Nato secretary general Anders Fogh Rasmussen, will be endorsed by Nato leaders at the Lisbon Summit, to be held next month, thereby replacing a document written in 1999.
The mission statement is expected to reflect on 21st-century threats such as cyber attacks, missiles from rogue states, global terrorism and piracy off the Somali coast.
The ministers will also discuss proposals to reform Nato's command structure to make the 28-nation alliance leaner and more efficient, according to Agence France-Presse.
The allies will also invest in a missile shield and resist deep national defence budget cuts despite difficult economic times, Rasmussen said.
He added that Russia should also cooperate in the anti-missile shield to ease concerns about the aims of the system.
US Secretary of Defence Robert Gates said a broader agreement on missile defence plans and the cost of linking Nato members into a common network was a relatively modest strategy.
