THE US and Russia had both emerged victorious at the end of the Cold War, former Soviet leader Mikhail Gorbachev said.
"I would not be making a mistake to say that perestroika won. It succeeded," he said during a celebration of the 20th anniversary of reforms that ultimately ended the hostilities between the two nations.
Mr Gorbachev also reflected on the current state of world affairs, noting the role of the US as the sole superpower.
"America has a right to be a leader," he said, adding that "this leadership should be realised through partnership, not domination".
Former US president Bill Clinton and former Secretary of State Colin Powell were among about 200 guests who attended what Mr Gorbachev described as a "meeting of old friends".
Mr Gorbachev is credited with engineering a series of reforms, called perestroika, in the Soviet Union that led to the fall of communism.
In 1990, he won the Nobel Peace Prize for his work.
"It was obvious from the beginning with perestroika blooming in Russia, there was a new openness, a new sense of freedom, there was a new leader," Mr Clinton said.
"He will go down in history as a person who changed the world for the better."
