U.S. President Donald Trump claimed on Friday that India and Russia appear to have shifted closer to China after this week’s Shanghai Cooperation Organization (SCO) summit in Beijing, where member states expressed strong backing for Chinese President Xi Jinping.

“The United States seems to have lost India and Russia to deep, dark China. May they have a long and prosperous future together!” Trump wrote in a post on his social media platform, Truth Social.

The SCO brings together China, India, Russia, Pakistan, Iran, Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan and Belarus, while 16 other nations participate as observers or dialogue partners. Member states described themselves as strengthened by the summit, a sentiment Trump appeared to echo in his remarks.

Ahead of the meeting, Russian President Vladimir Putin told China’s Xinhua news agency that the gathering would boost the SCO’s ability to address “modern challenges and threats” and reinforce solidarity across the Eurasian region.

Following bilateral talks with Xi, Putin added that relations between Russia and China had reached an “unprecedented level.”
