Cheng said Wen will hold bilateral meetings with some of the leaders on the sidelines of the SCO prime ministers gathering.
"This meeting is held at the right time and bears great significance," the vice foreign minister told reporters.
The meeting is expected to lay a solid foundation for future development of the SCO by implementing results of the SCO Beijing Summit held in June. Cheng said it will continue to deepen practical cooperation within the group by accelerating economic growth among its members, and will help lift the confidence and cohesion of SCO members by improving their capability to address external risks.
He added that, since the establishment of the SCO 11 years ago, it has grown into "a constructive force that plays a major role in geo-politics in the Euro-Asia region."
