Established formally in 2001, it grew out of a regional grouping aimed at seeking to define China’s borders with the former Soviet Union. Over time, it has expanded beyond its immediate neighbourhood to include countries as distant at Belarus and Sri Lanka as ‘dialogue partners’.

The current push to welcome both India and Pakistan is likely to further test the organisation’s already limited capability. The practical implications for Central Asia are unlikely to be dramatic, though in the longer term it may help bind Central and South Asia closer together and foster a greater sense of community across the Eurasian heartland.

In practical terms, the SCO has always been a fairly limited organisation. Seen initially by Russia as a way of controlling Chinese activity in Central Asia, for Beijing it has provided a useful umbrella under which to pursue their stealthy expansion in the region. For Central Asian powers, it provided another format in which to engage their larger neighbours. While the primary thrust of its activity has been in the security space, China has regularly sought to push it in an economic direction.
