The 2008 CAREC Transport and Trade Facilitation strategy identified six strategic corridors to be improved: Europe-East Asia, Mediterranean-East Asia, Russian Federation-Middle East and South Asia, Russian Federation-East Asia, East Asia-Middle East and South Asia, Europe-Middle East and South Asia. Although there have been improvements in customs administration, better co-ordination among custom offices is still needed. Furthermore, although intra-regional and extra-regional trade volume grew, the increase remained well below the assessed potential.
