[7] Ki was selected for the South Korean archery team alongside Joo Hyun-jung and Yun Ok-hee to contest the 2010 Asian Games in Guangzhou.

[3] She began the preliminary 72-arrow ranking round with a score of 671 points from a maximum of 720, tying her at the top of the standings for the women's individual event with teammate Lee Sung-jin and Chinese Taipei's Tan Ya-ting.

With a combined score of 1,993 points, Ki, Lee, and Choi Hyeon-ju also secured the number one seed for South Korea in the women's team competition.

[13] Ki won her second gold medal of the Games in the women's individual event contested later in the week, defeating Mexico's Aída Román in a closely fought final which necessitated a one-arrow shoot-off to determine the winner.

The pair both proceeded to shoot their arrows into the 8-ring of the target, but as Ki's effort was judged to have landed marginally closer to the centre, she was awarded the gold medal.

[15] Outside of the Olympics Ki delivered a strong performance in the 2012 Archery World Cup, beginning the competition with gold medals in the women's team and individual events at the opening stage in Shanghai.

[17] She qualified for the final stage held in Tokyo in September, where she advanced to the gold medal match and came from behind to defeat India's Deepika Kumari.

[21] In an interview in the newspaper JoongAng Ilbo published at the end of the year Ki reflected that her initial response to her non-selection was one of relief, having gained freedom the strict training regimen by which team members had to abide.

[19] Watching the archery competitions at the Asian Games that September, in which she performed commentary duties for the Korean broadcaster KBS,[23] motivated her to work to return to the national squad.

[25] Ki's subsequent victory over Choi in the final of the women's individual event represented her first gold medal win since the Archery World Cup almost three years earlier.

[33] Ki won her second Archery World Cup title in Odense in September, defeating Choi in the final to become the second female repeat winner in the tournament's history.
