BERLIN, Nov. 8 (UPI) -- In a public address to mark this weekend's 25th anniversary of the fall of the Berlin Wall, the former leader of the Soviet Union said the world could soon experience another Cold War.
At an event near Berlin's Brandenburg Gate, Mikhail Gorbachev said there are heightened tensions between Russia and the West over Ukraine, which had been part of the Soviet Union.
"The world is on the brink of a new Cold War. Some are even saying that it's already begun," Gorbachev said.
He accused the West, and the U.S. in particular, of succumbing to "triumphalism" following the 1991 collapse of the USSR.
Gorbachev, 83, advocated for Western governments to build a new trust with Moscow through dialogue and urged the lifting of sanctions enacted against senior Russian officials because of the country's action in eastern Ukraine.
There have been thousands of deaths in Ukraine since April when pro-Russian separatists took control in the regions of Donetsk and Luhansk.
Gorbachev's reforms when he was leader of the Soviet Union paved the way for the collapse of communism in eastern Europe and ultimately the Nov. 9, 1989 opening of the borders between East and West Berlin.
