Abstract
Shanghai Cooperation Organisation (SCO) is completing 20 years of its existence in 2021. Established in 2001, SCO has emerged as a regional organisation focusing on addressing three evils separatism, terrorism and extremism. For the two decades, SCO has transformed from remaining only a security-centric organisation to promoting business and cultural linkages across the member countries with various initiatives. End of the Cold War and post 9/11 world has enhanced the significance of multilateralism and regional organizations to not only balance power but also better regional cooperation. Pakistan joined SCO as an observer member in 2004 and continued to remain in the organisation after becoming its full member in 2017. Pakistan’s presence in SCO as an observer and later permanent membership of Pakistan has opened new avenues for cooperation and opportunities for Pakistan.
