Other team bosses also condemned the words spoken by Marko in a ServusTV interview in which he linked Sergio Perez's form to his cultural heritage and angered the driver's fellow Mexicans by placing the country in South rather than North America.
The comments created a stir on social media and led to a public statement from Marko as well as a personal apology to Perez.
Asked by Motorsport.com about the matter in an FIA press conference in Singapore, all the F1 team bosses stressed Marko was in the wrong.
"Stereotyping these days doesn't work anymore," said Haas team principal Guenther Steiner. "We need to be careful what we say.
"Sometimes it's very difficult to do, because what you say, you don't mean it, and then you shouldn't say it, obviously, if you're aware of it.
"I didn't hear it, because I could have understood in German how it was said, so I just read it, and maybe in translation it maybe sounds different.
"But I think it is what it is. And I think they are dealing with it. And I was surprised to hear that Mexico was in South America!"
Wolff made it clear that he took the matter very seriously, and that it was not good for F1 as a whole.
"We're laughing about South America," said the Austrian. "But it's a topic that's not at all funny. And it's not only what has been said, but it's the mindset, that you can even come up with these things. And that hasn't got any place in F1.
"That's not something that should have been said in the past, and certainly not now, and in the future.
"We all know that we need more diversity in F1, more inclusion, and the teams do their best to create an environment where this is possible. And obviously statements like this don't shine the light on F1 that F1 deserves for all of the activities."
McLaren's Zak Brown echoed his colleagues: "It was not a great comment, you can understand why people were offended by it. I didn't hear it myself. I've only read it. But you have to be very
respectful of everyone, and not make comments that can be viewed inappropriately."
In a separate Sky Sports F1 interview Marko's Red Bull colleague Christian Horner made it clear that he didn't approve of what was said, while stressing that the veteran Austrian has learned from it.
"Firstly those comments, they weren't right," he said. "Helmut quickly recognised that and apologised for that both publicly and directly to Sergio.
"He spoke directly to Sergio about it, and I think you're always learning in life, even at 80 years of age, and inevitably lessons have been learned.
"Checo is a massively popular member of our team, he's an important member of our team and we pushed very hard to sign him back for the 2021 season.
"We have a huge following around the world and we take that very seriously, very responsibly and the fan following not just that Checo has but the team has and F1 has, we're very conscious of. This is his 250th race, we want to focus on that."
Regarding the lack of an official comment from the team itself, he said: "From Helmut's perspective, he's apologised. He's not an employee of Red Bull Racing, so in terms of why didn't we put out a statement, he's part of the Red Bull wider group, and the group issued that apology through the ServusTV channel."
