The Shanghai Cooperation Organisation (SCO) comprises Russia, China, Kazakhstan, Kyrgyzstan, Tajikistan and Uzbekistan. It was set up on the basis of the Agreement on Military Confidence-Building Measures in Border Regions and the Agreement on the Mutual Reduction of Armed Forces in Border Regions signed between Kazakhstan, Kyrgyzstan, Russia and Tajikistan on the one hand, and China on the other hand in 1996 and 1997, respectively.

The Charter is the basic statutory document sealing the goals, principles, structure and guidelines of the SCO operation.

The Treaty of Long-Term Neighbourliness, Friendship and Cooperation, signed in Bishkek, Kyrgyzstan, on August 16, 2007, was a major step towards strengthening the legal foundation of the organisation. It created conditions for advancing the sides' multilateral cooperation to a fundamentally new level. As of now, Kyrgyzstan, China, Russia, Tajikistan and Kazakhstan have ratified the treaty.
