The Shanghai Cooperation Organisation (SCO) is a Eurasian political, economic, international security and defence organization established by China and Russia in 2001. It is the world's largest regional organization in terms of geographic scope and population, covering approximately 80% of the area of Eurasia and 40% of the world population. As of 2023, its combined GDP based on PPP was around 32% of the world's total. The SCO is the successor to the Shanghai Five, formed in 1996 between the People's Republic of China, Kazakhstan, Kyrgyzstan, Russia, and Tajikistan. In June 2001, the leaders of these nations and Uzbekistan met in Shanghai to announce a new organization 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. The SCO is governed by the Heads of State Council (HSC), its supreme decision-making body, which meets once a year. The organization also contains the so-called Regional Antiterrorist Structure (RATS).
