Malala Yousafzai, an advocate for women's education and the youngest person to become a Nobel Laureate, urged Prime Minister Shinzo Abe on Friday to take the initiative in expanding educational opportunities for female youth at the Group of 20 summit this summer.

"I spoke with the prime minister today about girl's education. The importance of investing in girls now — for a future in economic growth and global stability," Malala said at a news conference after her short meeting with Abe at his official residence.

The meeting preceded the joint summit of the World Assembly for Women and the W20 being held in Tokyo on Saturday.
