Shamba made the comments at the outcome of UN-sponsored security talks with Georgian Minister for Conflict Resolution Giorgi Khaindrava in Abkhazia's southern Gali district.
The meeting was aimed at defusing tension in the region following a series of armed incidents that claimed the lives of several civilians.
Georgia blames separatist forces for the unrest. Abkhazia in turn accuses Georgian paramilitary units of escalating tension with a view to force the departure of Russian peacekeepers.
Russian troops have been stationed in Gali since Abkhazia forcibly won de facto independence from Georgia in the early 1990s.
