In response to a Latvian government request for assistance in assuring the security of the Riga Summit in November 2006, NATO provided technical security, CBRN response capabilities, air and sea policing, improvised explosive device (IED) detections, communications and information systems and medical evacuation support.
Given the context and the ex-Soviet past of the three Republics, a No-Fly Zone was established to protect the meeting, which strengthened the NATO air protection already active in the region. The meeting had a symbolic consequence: it was perceived as a way to increase the visibility of the three Baltic states as members of NATO.
