Leaders of the Shanghai Cooperation Organisation, including Russia's Vladimir Putin and China's Xi Jinping formally signed off on the duo's accession at the annual summit in Kazakhstan's capital Astana.
Pakistan and India on Friday formally joined the Shanghai Cooperation Organisation, a security bloc spearheaded by China and Russia, despite tensions bubbling over disputed Kashmir.
Leaders of the bloc — including Russia's Vladimir Putin and China's Xi Jinping — formally signed off on the sub-continent duo's accession at the annual SCO summit in Kazakhstan's capital Astana.
Pakistani Prime Minister Nawaz Sharif and Indian counterpart Narendra Modi reportedly shook hands and exchanged greetings late on Thursday at the opening of the SCO meeting, although New Delhi said that no formal bilateral meeting between the two nuclear rivals was planned.
Modi, Sharif hail landmark moment
Modi on Friday hailed India's accession as a "landmark moment in the journey of the SCO" and pledged India would play a "constructive and active role" in the organisation that also includes ex-Soviet states Kyrgyzstan, Kazakhstan Tajikistan and Uzbekistan.
Sharif thanked the founding members for their "staunch support" for his country's entry into the organisation, which he hailed as "an anchor of stability in the region."
Muslim-majority Kashmir has been divided between Pakistan and India since the end of British colonial rule in 1947. Both claim the territory in its entirety. Anti-India sentiments run deep in India-administered Kashmir where the majority of population want independence or a merger of the territory with Pakistan.
India regularly accuses Pakistan of arming rebels, while Islamabad denies the allegation, saying it only provides diplomatic support to Kashmiris seeking self-determination.
But both Moscow and Beijing expressed optimism that the two neighbours' entry into the SCO could strengthen prospects for peace across the region.
Managing competing interests
Founded in 1996, the SCO is viewed as a vehicle for managing competing Chinese and Russia political, economic and military interests in the strategic region.
China is championing ambitious infrastructure projects, including land and sea links touted as a revival of the ancient Silk Road trade route.
Russia, in turn, has focused on broadening its Eurasian Economic Union integration project involving former Soviet allies.
