Iran signs memorandum to join Asian security body founded by Russia, China

Iran has signed a Memorandum of Obligations to become a permanent member of the Shanghai Cooperation Organisation (SCO), Iran's foreign minister said on Thursday, as Tehran seeks to overcome economic isolation amid U.S. sanctions.

"By signing the document for full membership of the SCO, now Iran has entered a new stage of various economic, commercial, transit and energy cooperation," Hossein Amirabdollahian wrote on his Instagram page.

Last year, the rapidly-expanding central Asian security body, whose founding heavyweights are China and Russia, approved Iran's application for accession, while Tehran's hardline rulers called on members to help it form a mechanism to avert sanctions imposed by the West over its disputed nuclear programme.

Iranian President Ebrahim Raisi was in the Silk Road oasis of Samarkand, Uzbekistan on Thursday to attend a summit of the organization. He was expected to meet Russian President Vladimir Putin, Iranian media reported.
