The United States is isolating itself from countries around the world, and making countries unite in a time of economic repression from Washington, prominent investor Jim Rogers says.

"America is pushing China and Russia together, America's pushing China and Iran together, pushing China, Iran, Russia all together, and that's pushing America out of some very major countries in the world," Rogers told Sputnik news agency after the St. Petersburg International Economic Forum (SPIEF).

An American investor now living in Singapore, Rogers says that because of US politics, American businessmen are getting much fewer opportunities to invest. "There are plenty of opportunities in Asia, just fewer and fewer because America is getting in spats with more and more countries. That's all. It's a big world out there, there's plenty left, it is just a shame to be cutting some of these places out,"he said.
