My comment: I do not know Russian language. The English-language official reports from Russia that I can find is this only*:
Yelizaveta Isakova, SCO Considers Admission of New Countries. Voice of Russia, June 16, 2011 (available now)
http://indrus.in/articles/2011/05/16/sco_considers_admission_of_new_countries_12522.html
("But last year, when it came to Iran’s entry, it was decided that no state against which the UN Security Council imposed sanctions, could be a member of the organization. The SCO made it clear to Teheran that it cannot count on the membership in the organization before it resolves the problems linked with its nuclear program. Teheran seemed to understand the hint")
The quotation backs up one aspect of the above VOA report.
* Another is
Medvedev calls for closer ties between Afghanistan, Shanghai alliance. RIA Novosti, May 15, 2011
http://en.rian.ru/world/20110615/164623326.html
, which has nothing to do with the VOA report.
