What exactly does 'further action' mean?

To the French and to the Germans, it probably means more discussion, no?

The United Nations Security Council today passed a resolution ordering Syria to co-operate with the investigation into the murder of former Lebanese prime minister Rafik Hariri - or face "further action".

The resolution orders Damascus to arrest and freeze the assets of anybody the UN suspects of involvement in the killing. It was passed unanimously.

Although no Syrian officials have yet been designated as suspects in the Hariri murder, a UN inquiry led by Detlev Mehlis, a German prosecutor, has implicated President Bashar Assad’s brother and brother-in-law, as well as the former heads of military intelligence and internal security.

Assad should hand over his brother...but why am I skeptical the UN won't really do anything?
