Ivanka, who owns a jewellery and clothing line, was present alongside Prime Minister Theresa May, German chancellor Angela Merkel and Chinese president Xi Jinping. The White House said Ivanka "briefly joined the main table when the President had to step out", according to the AFP.

One official who was watching the session said she has taken her father's place at the table on at least two occasions today and did not speak.
The initiative was launched here by World Bank President Jim Yong Kim in the presence of Ivanka Trump and her father as also G20 host Angela Merkel and other world leaders, including Canadian Prime Minister Justin Trudeau and International Monetary Fund chief Christine Lagarde. Trump has said the USA will commit $50 million United States to the Women Entrepreneurs Finance Initiative (We-Fi).
"If she weren't my daughter it would be so much easier for her", the president said with a laugh, according to the New York Post.
Her appointment in March as an official unpaid advisor to her father's White House adminstration spraked fury and accusations of nepotism. Trump's senior staff is dominated by men, despite the considerable influence of Ivanka Trump, who serves as a senior White House adviser. Just a few weeks ago Ivanka professed to want to avoid getting involved in politics. "I have to tell you that, from day one", he said.
