(EPC/SAM) Lying at the crossroads between East and West and South and North, the South Caucasus is situated at the intersection of Eurasia's major energy and transport corridors. An important geostrategic region, for centuries it has been the theatre of competition between regional powers, including the Persian, Russian, and Ottoman Empires. While these empires may have disappeared, their successor states continue to jostle for influence along with new players, including the US, NATO, EU and China. Hence, despite being independent for more than two decades, the three South Caucasus states – Armenia, Azerbaijan and Georgia – continue to feel the influence and, in some cases, threat, of external actors.
