Angela Merkel and Ivanka Trump meeting in Washington earlier this month
Ivanka, despite hostilities between her father and Mrs Merkel, seemed to get on well with the German Chancellor.
The two were seen laughing and exchanging trivialities after Merkel met with the US president earlier this month.
Ivanka has now been invited to attend a women's economic summit in Germany where she will join Mrs Merkel.
She is due to fly to Berlin to join women from other G20 countries and four additional US delegates.

She wrote on Twitter: "Looking forward to promoting the role of women in the economy and the future of our workforce globally #W20".
The W20 focuses on women's empowerment and looks into apprenticeships for women, financial and business advice and closing the gender pay gap.
A White House official said Mrs Merkel's staff reached out to Ivanka about setting up the meeting.
Mrs Trump is more and more stepping in to act as an unofficial White House liaison.
