Kim Yo-jong and North Korea's ceremonial head of state Kim Yong-nam were sitting beside International Olympic Committee president Thomas Bach here, as a unified Korea team played in the Games for the first time.
The two leaders however, did not discuss North Korea's invitation to Moon to visit Pyongyang, according to a senior administration official. However, the U.S. Treasury Department past year included on its list of blacklisted officials over her position as vice director of the ruling Workers' Party's Propaganda and Agitation Department. The meeting is set to come at a time when the United States government under the leadership of President Donald Trump is preparing to continue the policy of maximum pressure against North Korea by imposing more economic sanctions to the repressive regime of Kim Jong Un.
