It was led by President of the Presidium of the DPRK Supreme People's Assembly (SPA) Kim Yong Nam, who was accompanied by first vice department director of the Central Committee of the Workers' Party of Korea (WPK) Kim Yo Jong.
United States president Donald Trump's daughter Ivanka Trump will also be attending-she lands in South Korea tomorrow (Feb. 23), and will have dinner with South Korean president Moon Jae-in.
"For all those in the media who think I should have stood and cheered with the North Koreans, I say, the United States of America does not stand with murderous dictatorships - we stand up to murderous dictatorships", Pence told the crowd of conservatives, referencing media criticism of his behavior at the 2018 Winter Olympic Games in Pyeongchang.
Ivanka Trump will also attend the closing ceremony. In that previous role, he was accused of planning an attack on the Cheonan, a South Korean warship, that killed 46 sailors and the shelling of South Korea's Yeonpyeong island in 2010, when he was head of military intelligence.
Ivanka did not plan to meet officials from North Korea, said the officials on Wednesday on the condition of anonymity, Xinhua news agency reported. Kim Yo-jong, the younger sister of the North Korean leader Kim Jong-un, and U.S. Vice President Mike Pence were set to meet on February 10 at the Blue House, but the North pulled out at the last minute. Kim is also blacklisted by both the US and South Korea.
Ri Son Gwon will travel with Kim Yong Chol for the Games closing ceremony.
Ivanka Trump is scheduled to meet South Korean President Moon Jae-in on Friday, another salvo in that diplomatic back-and-forth.
Pyongyang has used the Games to try to soften its image and push for talks with Seoul that could cut the odds of a U.S. military strike.
It added that "following a comprehensive assessment, the government of Japan strongly suspects that they conducted ship-to-ship transfers banned" by the UN Security Council resolutions.
Sen. Risch, a member of the USA delegation, also maintains a hardline position toward the North.
