Watch: Jacinda Ardern, Sanna Marin give fitting reply to reporter's sexist question

“We, of course, have a higher proportion of men in politics, it's reality. Because two women meet, it is not simply because of their gender."

Arden said Finland exports into New Zealand NZ $199 million worth of exports and cited examples of trade deals between the two countries.

“Yeah, now we are meeting because we are prime ministers, of course,” Sanna Marin, 37, said.

In 2017, Ardern became New Zealand's youngest prime minister at 36 when she took office through a coalition deal after an inconclusive election. The next year, she became the second prime minister in the world - after Pakistan's Benazir Bhutto - to give birth while in office, later taking her daughter onto the floor of the UN Assembly in New York.

Marin was appointed as Finland Prime Minister in 2019 at the age of 34. She was not only the youngest prime minister of the northern European nation, but the youngest head of state of an country in the world.

Earlier this year, videos of her partying with friends surfaced on social media, sparking a controversy. She was eventually cleared of misconduct following an official inquiry. The probe concluded that Marin had not neglected her duties as prime minister.

At the time of the scandal, Marin said she spent "an evening with friends" and that the videos were "filmed in private premises".

"I am human. And I too sometimes long for joy, light and fun amidst these dark clouds," she said.
