The Shanghai Cooperation Organisation (SCO) was established on 15 June 2001 in Shanghai by China, Russia, Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan. It evolved from the "Shanghai Five" mechanism created in 1996 to resolve post-Soviet border disputes and demilitarise frontier zones between China and its western neighbours. Uzbekistan's accession in 2001 transformed the grouping into a formal multilateral organisation.
The SCO's foundational document is the SCO Charter, signed in Saint Petersburg in June 2002 and entered into force in 2003. Its declared priorities are captured in the so-called "three evils" doctrine: combating terrorism, separatism, and extremism. This security agenda is operationalised through the Regional Anti-Terrorist Structure (RATS), based in Tashkent, and through joint military exercises such as the recurring "Peace Mission" drills.
Membership has expanded substantially. India and Pakistan were admitted as full members at the 2017 Astana summit, Iran joined in 2023, and Belarus became a full member at the 2024 Astana summit. The organisation also maintains categories of observer states and dialogue partners, including states such as Mongolia, Afghanistan, Turkey, and several Gulf countries.
Institutionally, the SCO operates through an annual Council of Heads of State summit, a Council of Heads of Government, a Secretariat in Beijing, and rotating chairmanship. Decisions are taken by consensus, which limits the bloc's ability to act on contentious bilateral disputes (for example, the India–Pakistan or India–China rivalries).
Analysts debate whether the SCO functions as a genuine security alliance, an anti-Western coalition, or primarily a norm-setting forum that legitimises authoritarian governance models and Chinese-Russian regional leadership. Unlike NATO, it has no mutual-defence clause and no integrated command. Its economic agenda — including discussions of an SCO development bank and local-currency settlement — has progressed slowly due to divergent interests between Beijing and Moscow.
Example
At the July 2024 Astana summit, SCO leaders formally admitted Belarus as the organisation's tenth full member, with President Alexander Lukashenko signing the accession memorandum.
Frequently asked questions
No. The SCO has no mutual-defence clause or integrated command. It coordinates counter-terrorism, intelligence-sharing, and joint exercises, but members retain full autonomy over their defence policies.
