United States 40th President, Ronald Reagan made racist remarks about African delegates to the United Nations, calling them “monkeys” and saying they were still “uncomfortable wearing shoes”, newly released audio recordings have revealed.

Reagan, the actor turned politician who was a popular two-term president, made the comments in a phone call with the disgraced then President Richard Nixon as the two discussed a 1971 vote by the UN to recognize China, instead of the US ally Taiwan.

At the time of the call, Nixon was still president and Reagan was governor of California.

The two were discussing the Tanzanian delegation’s reaction to the vote, after delegates danced in the chamber.

“To watch that thing on television, as I did, to see those, those monkeys from those African countries – damn them, they’re still uncomfortable wearing shoes!” Reagan tells Nixon, who erupts in laughter.

The recording was first published in the Atlantic magazine in an article written by Tim Naftali, who directed the Richard Nixon Presidential Library and Museum from 2007 to 2011.

The news comes as the current occupant of the Oval Office, Donald Trump, is engulfed in controversy after making racist remarks about the city of Baltimore and a black congressman whose district partially covers the city.

Trump – who frequently uses racist or racially charged language – called Baltimore a “rat and rodent-infested mess” and the “worst in the USA”.

In the Atlantic, Naftali writes that the conversation between the two men had been originally released in 2000 with the racist portion removed “to protect Reagan’s privacy”.

After Reagan’s death in 2004, the privacy concerns were eliminated, and last year Naftali requested the full release of the recordings. They were released earlier this month by National Archives, which made them available online.
