Watch: Putin, Modi and other world leaders in China for summit

Russian President Vladimir Putin and Indian Prime Minister Narendra Modi are among the twenty world leaders attending a regional security summit in China.

Xi Jinping, China's president, is also holding talks with Modi ahead of the annual gathering of the Shanghai Cooperation Organisation (SCO) in the port city of Tianjin. It is Modi's first time in China in seven years.

The summit comes as US President Trump has imposed steep tariffs on Indian goods as punishment for Delhi's continued purchase of Russian oil, and Putin faces threats of sanctions for his ongoing war on Ukraine.
