It was supposed to be an event showcasing Group of 20 leaders' commitment to better empowering women in employment, economy and education. But only two of the world leaders on stage were women.

Titled the Special Event on Women's Empowerment, the only female world leaders in attendance were outgoing British Prime Minister Theresa May and German Chancellor Angela Merkel.

Still, G20 leaders on Saturday reiterated their shared recognition that "gender equality and women's empowerment are essential for achieving inclusive and sustainable society and economic growth," according to their joint statement.
