What Is the Role of Russia in Regional Security?

The siestio is an alliance of six countries, including russia and sajakistan. It was set up to protect the interests of its member states against external threats. But it's not as if it's aimed at invading any other place, but rather protecting its own members. i wouldn't really think of nato being an exact equivalent to siestio, because while the paradime is very similar, the two organizations are very different.
