But the U.S. president's daughter spent part of her weekend sitting around a table with the Chinese, Russian and Turkish presidents, the German chancellor and the British prime minister.
Also at the G20, Donald Trump and his daughter spoke at an event in which the president announced the USA would commit $50 million toward a fun to empower women.
They also stressed that "when other leaders stepped out, their seats were also briefly filled by others".
In an interview with "Fox and Friends" last week, Trump said she tries to stay away from politics, despite having a White House role that has expanded since she became a volunteer "assistant to the president", a job that carries ethical obligations without pay. Trump has said the USA will commit $50 million United States to the Women Entrepreneurs Finance Initiative (We-Fi).
Donald Trump's daughter and adviser Ivanka Trump took her father's seat at the G20 economic summit at least twice Saturday, and the internet is not having it. Assuming Bloomberg's reporting is correct that she took the president's seat a few times, it's not clear what was being discussed on the other occasions.
Following the incident, she said: "I understand why he has to do this-to prove he's a man".
However, Russia's summit representative tweeted that when President Trump was out of the room for bilateral meetings, the first daughter sat in a replacement.
There is no report of Ivanka actually being any more involved than on any other "Bring Your Child To Work Day" might be, but even her presence at the top table is enough to have evoked a stern reaction.
President Trump announced on Saturday that the USA was pledging $50 million to Ivanka's entrepreneurship fund, however.
Although she does have a White House position, many people questioned if she was really qualified to take on such a task, as absences at the G-20 summit are usually covered by high-ranking state officials.
Russian Federation has denied meddling, and Putin said yesterday that in the meeting, "I got the impression that my answers satisfied him" and that Trump "agreed". "Might be the only bad thing she has going, if you want to know the truth".
"I am very proud of my daughter Ivanka", he said.
