India announced on Sunday that Prime Minister Narendra Modi will attend the summit of the Shanghai Cooperation Organization.
The two-day meeting of the security and economic cooperation framework will be held in Samarkand, Uzbekistan, starting on Thursday.
Russian President Vladimir Putin and Chinese President Xi Jinping also reportedly will attend the talks.
The Indian government says Modi is likely to hold a few bilateral meetings on the sidelines of the summit.
Amid China's increasing maritime activities, India is taking part in a four-nation framework called the Quad. The other three member countries are Japan, the United States and Australia.
Meanwhile, India has been shying away from directly criticizing Russia for its invasion of Ukraine. Instead, it has sharply increased crude oil imports from Russia.
Many eyes are on what stance India will take toward Russia and China at the upcoming talks.
