SEOUL, South Korea — North Korean leader Kim Jong Un’s younger sister is among the officials who were awarded key posts at the country’s ruling-party congress, state media said Tuesday.

The Korean Central News Agency reported that Kim Yo Jong was named a member of the Workers’ Party of Korea’s Central Committee during the congress that ended Monday.

State media has also said Kim Yo Jong has served as a vice department director at the ruling party. Believed to be in her late 20s, she frequently appears at her brother’s public events, standing out amid elderly male officials.

While the new post raises Kim Yo Jong’s profile, it does not elevate her to North Korea’s No. 2 position, as some North Korea-watchers had speculated might happen during the congress.
