"Taking into account the climate emergency and worldwide unrest, it's not an exaggeration to say that 2020 and the next few years will determine not only the fate of Xi and Trump, but also the fate of the world", he said.
"And I would like to see it realized while I am still around", he told journalists on the sidelines of the World Economic Forum in Davos, Switzerland.
Soros also announced he will launch "the most important project of my life" - a $1 billion investment in "critical thinking" via a new network of colleges.
"We live at a transformational moment in history". "The strongest powers, the U.S., China and Russian Federation remained in the hands of would-be or actual dictators and the ranks of authoritarian rulers continued to grow", he said.
Soros also assailed Trump's economic policies, saying he "has managed to overheat an already buoyant economy. An overheated economy can't be kept at the boiling point for too long", cautioned Soros. "The survival of open societies is endangered and we face an even greater crisis: climate change", he said.
"If all this had happened closer to the elections, it would have assured his re-election". "The biggest and most frightening setback occurred in India where a democratically elected Narendra Modi is creating a Hindu nationalist state, imposing punitive measures on Kashmir, a semi-autonomous Muslim region, and threatening to deprive millions of Muslims of their citizenship", he said. "His problem is that the election is still 10 months away and, in a revolutionary situation, that's a lifetime".
Billionaire philanthropist George Soros has launched a stinging attack on the "authoritarian rulers" of both the U.S. and China.
He described the plan of the Open Society University Network as "the most important project of my life" and said it would be an global platform for teaching and research that universities worldwide would be able to join.
During the speech he also took aim at China's Xi Jinping who he said was "trying to exploit Trump's weaknesses" and is using 'artificial intelligence to have total control of his people'.
Soros, whose Central European University (CEU) was forced to leave Hungary after pressure from the government of Prime Minister Viktor Orban, said the project was needed at a time when open society was at more risk than ever.
