Shanghai Cooperation Organisation
The Shanghai Cooperation Organization (SCO) is a Eurasian political, economic and international security organisation of ten member states. It focuses on political, economic, security and counter-terrorism cooperation.
It is the world's largest regional organisation in terms of geographic scope and population, covering at least 24% of the world's total area (65% of Eurasia) and 42% of the world population. As of 2024, its combined nominal GDP accounts for around 23%, while its GDP based on PPP comprises approximately 36% of the world's total.
The SCO is the successor to the Shanghai Five, formed in 1996 between China, Kazakhstan, Kyrgyzstan, Russia, and Tajikistan. In June 2001, the leaders of these nations and Uzbekistan met in Shanghai to announce the SCO, a new organisation with deeper political and economic cooperation. In June 2017, it expanded to eight states, with India and Pakistan. Iran joined the group in July 2023, and Belarus in July 2024. Several countries are engaged as observers or dialogue partners. Its most recent meeting was held in September 2025 in Tianjin, China.
The SCO is governed by the Heads of State Council (HSC), its supreme decision-making body, which meets once a year. The organisation also contains the Regional Anti-Terrorist Structure (RATS).
The Shanghai Five group was created on 26 April 1996 when the heads of states of China, Kazakhstan, Kyrgyzstan, Russia and Tajikistan signed the Treaty on Deepening Military Trust in Border Regions in Shanghai.
On 24 April 1997 the same countries signed the Treaty on Reduction of Military Forces in Border Regions in a meeting in Moscow, Russia. On 20 May 1997, Russian President Boris Yeltsin and Chinese leader Jiang Zemin signed a declaration on a "multipolar world".
Subsequent annual summits of the Shanghai Five group occurred in Almaty, Kazakhstan in 1998, in Bishkek, Kyrgyzstan in 1999, and in Dushanbe, Tajikistan in 2000. At the Dushanbe summit, members agreed to "oppose intervention in other countries' internal affairs on the reason of 'humanitarianism' and 'protecting human rights;' and support the efforts of one another in safeguarding the five countries' national independence, sovereignty, territorial integrity, and social stability." The Shanghai Five structure helped speed up the members' resolution of border disputes, agree on military deployments in border areas, and address security threats.
In 2001, the annual summit returned to Shanghai and the group was institutionalised. The five member nations first admitted Uzbekistan in the Shanghai Five mechanism. On 15 June 2001, all six heads of state signed the Declaration of Shanghai Cooperation Organisation, praising the role played thus far by the Shanghai Five mechanism and aiming to transform it to a higher level of cooperation. From 2001 to 2008, the SCO developed rapidly, establishing a number of permanent bodies and ad hoc initiatives dealing with economic and security matters.
