Chinese President Xi Jinping gathered the leaders of Russia and India among dignitaries from around 20 Eurasian countries on Sunday for a showpiece summit aimed at putting China front and center of regional relations.

Security was tight in the northern port city of Tianjin, where the Shanghai Cooperation Organization summit is being held until Monday, days before a massive military parade in the capital Beijing to mark 80 years since the end of World War II.

The SCO comprises China, India, Russia, Pakistan, Iran, Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan and Belarus — with 16 more countries affiliated as observers or "dialogue partners."
