This ‘International North-South Transit Corridor’ has assumed much more importance since the invasion. It allows Russia to access Asian markets - including arms transfers - in ways it hopes are less vulnerable to international sanctions.

Russia is highly likely investing in OWA-UAVs because it provides Russia with a relatively cheap long-range strike capability at a time when it has expended a large proportion of its cruise missile stocks in Ukraine.
