SEOUL, South Korea — North Korea plans to send a high-level government delegation to South Korea to attend the opening ceremony of the Winter Olympics this week, South Korean officials said on Sunday.

The 22-member delegation will be led by Kim Yong-nam, the president of the Presidium of North Korean Parliament, the South Korean government announced, citing a notice it received from the North late Sunday.

The group’s three-day visit will start on Friday, when the opening ceremony will be held in the South Korean town of Pyeongchang.

Mr. Kim, who is not related to Kim Jong-un, the country’s supreme leader, is often referred to as North Korea’s nominal head of state because he receives visiting heads of state, approves the credentials of ambassadors and represents North Korea on state visits abroad. He led the North Korean delegation to the 2008 Summer Olympics in Beijing.
