Iran and the SCO: The Quest For Legitimacy and Regime Preservation

At the 2021 Shanghai Cooperation Organization (SCO) summit in Dushanbe, Tajikistan, the bloc announced the approval of Iran's longstanding bid for membership. The Islamic Republic has viewed its involvement in the organization as a means of bolstering external legitimacy, fostering security-oriented regionalism, and promoting the transition toward the so-called multipolar world order. The SCO, led by Russia and China, has served as a regime-preservation network by providing Iran with a source of solidarity against external pressure. Tehran's commitment to the normative order, sustained by the SCO's discourse of noninterference, sovereignty, and countering the "three evils"—terrorism, extremism, and separatism—has galvanized the organization's role as a common front against the imposition of liberal norms and challenges to regime security.
