Putin said at the G20 summit that Russia has presented examples of terrorism financing by individual businessmen from 40 countries, including from member states of the G20.
"I provided examples related to our data on the financing of Islamic State units by natural persons in various countries. The financing comes from 40 countries, as we established, including some G20 members," Putin told reporters following the summit.
The fight against terrorism was a key topic at the summit, according to the Russian leader.
"This topic (the war on the terror) was crucial. Especially after the Paris tragedy, we all understand that the means of financing terrorism should be severed," the Russian president said.
Russia has also presented satellite images and aerial photos showing the true scale of the Islamic State oil trade.
"I've demonstrated the pictures from space to our colleagues, which clearly show the true size of the illegal trade of oil and petroleum products market. Car convoys stretching for dozens of kilometers, going beyond the horizon when seen from a height of four-five thousand meters," Putin told reporters after the G20 summit.
The Russian president also said that Syrian opposition is ready to launch an anti-ISIL operation if Russia provides air support.
