Zhang Zhehui from China and Mami Umeki from Japan shared bronze.
Jeong and Sol had some skirmishes in the four-minute battle, but neither was able to put down decisive techniques. In the end, the winner was decided based on the number of penalties.
“Preparing for the Asiad, the training was so hard that I wanted to give up,” said Jeong. “I want to thank my coach and staff who led me to this stage.”
Last year, Jeong had beaten Sol at the Asian Judo Championships last year.
Sol had been involved in another inter-Korean match in judo four years ago, having lost to the South’s Hwang Ye-sul in the women’s 70㎏ at the Guangzhou Asiad after using a banned technique.
The North Korean judoka later on moved up to the under 78kg weight class and won the 2013 world championship.
