Buenos Aires: Russian President Vladimir Putin walked up to Saudi Arabia's Crown Prince Mohammed bin Salman at a summit of G20 world leaders, high-fived him and then shook his hand heartily.
Putin's exuberant greeting of the prince was seen as over the top and promptly went viral.
Their embrace comes amid reports that Russia and Saudi Arabia have reached a pact to cut oil production when the OPEC cartel meets on December 6 in Vienna, to help shore up collapsing crude prices.
Kirill Dmitriev, the chief of Russia's sovereign wealth fund, told reporters that Putin would meet the prince Saturday and discuss boosting Saudi Arabia's $2 billion investment in Russia.
The prince was also seen chatting with President Donald Trump and his daughter Ivanka.
He also also discussed investments and economic partnerships with Prime Minister Narendra Modi and Chinese President Xi Jinping. Modi and the prince discussed scaling up investments in India's tech, farm and energy sectors, according to an Indian official.
