President Moon Jae-in has sent gifts to two nurses in Austria who decades ago helped treat people in South Korea who had leprosy.
The nurses, now in their 80s, are named Marianne Stoeger and Magaret Pissarek.
For about 40 years, they looked after people with leprosy on Sorok-do Island the place where Koreans with the disease were quarantined.
They returned to Austria in 2005 after their own health deteriorated.
President Moon sent a personal message wishing them the best of health, along with gifts of red ginseng and blankets, via South Korea's Ambassador to Austria.
Moon was in Austria last week for a state visit but was unable to meet with them in person because they live far away from Vienna.
Seoul's top office said the nurses sent a reply expressing gratitude to the president of what they called their "second hometown."
The nurses become honorary South Korean citizens in 2016.
