Khurshid also went to Uzbekistan where he had bilateral talks with its Foreign Minister Abdulaziz Kamilov.
The highlight of the Khurshid's visit was the meeting with Aziz in which Pakistan informed India that it has named a new prosecutor for the much-delayed Mumbai attacks trial and will send a judicial commission on September 23 to cross-examine key Indian witnesses.
The Indian minister also told Aziz that there has to be a "conducive atmosphere" for a meeting between the premiers of the two countries in New York later this month.
Addressing the SCO's Heads of State Summit in Kyrgyzstan capital Bishkek, Khurshid reiterated India's stand that it is ready to play a larger role in SCO as a full member, once the organisation reaches consensus on its expansion.
He also expressed India's desire to deepen its security-related cooperation with the SCO's Regional Anti-Terrorism Structure (RATS) in particular.
He also held talks with Iranian President Hassan Rouhani and Kyrgyz leaders during the summit.
After Kyrgyzstan, Khurshid went to Uzbekistan capital Tashkent where he had bilateral talks with his counterpart Kamilov. He also chaired a regional conference of Indian heads of mission there.
