The leaders will adopt important organizational decisions to further enhance cooperation among SCO member states and approve the organization’s budget.

Established in June 2001 in Shanghai, the SCO is an intergovernmental organization with nine member states.

The organization’s key objectives are to strengthen relations among member states and promote cooperation in political affairs, economics, and trade, scientific-technical, cultural, and educational spheres, as well as in energy, transportation, tourism, and environmental protection, while also ensuring regional peace, security, and stability.

Its founding countries include China, Kazakhstan, Kyrgyzstan, Russia, Tajikistan, and Uzbekistan, while Pakistan became a member of the SCO in June 2017 after previously getting an observer status.
