South Korean president Moon Jae-in declared the Pyeongchang Winter Paralympics open during a spectacular ceremony that comes amid an Olympics-driven inter-Korean thaw.
After cultural and dance performances and a parade by the athletes, Mr Moon officially opened the biggest Paralympics in history.
Two North Korean skiers took part in the parade under their own flag, making them the first athletes from the North to compete in a Winter Paralympics.
It is the latest sign of an intense rapprochement between the Koreas that began at the Winter Olympics in February.
The thaw prompted a flurry of diplomatic activity. In the latest development, US president Donald Trump agreed to hold a meeting with the North's leader Kim Jong-un.
