"Although the Riga Summit is not a summit on NATO enlargement as such, as you know, NATO allies will soon begin drafting exact language on a signal we want to send to countries who aspire NATO membership.  How exactly that signal will look like is a bit difficult to say, but I think I'm not far off the mark if I say it will be an encouraging signal to them.."

- Jaap de Hoop Scheffer,
NATO Secretary General
