EXO has also previously performed at the opening ceremony of the 2014 Incheon Asian Games.
President Moon Jae In was also captured shaking hands with Kim Yeo Jong, the youngest sister of Kim Jung Un.
President Moon Jae-in declared the Games open and watched as South Korea's 2010 Olympic gold medallist, Kim Yuna, lit the Olympic cauldron which will burn throughout the Games.
Trump, who has at times exchanged taunts and threats with Kim, said in early January after the first intra-Korean talks in over two years that the United States was willing to speak to North Korea "under the right circumstances", although it was far from clear whether this would pay dividends.
Moon gave qualified consent to holding a future summit with Kim, the first between the two Koreas since 2007.
Both of those South Korean presidents had struggled under growing domestic criticism after their trips to Pyongyang had resulted in large shipments of aid and investment but failed to end the North's nuclear weapons program.
"We will try our hardest to win more glory in Pyeongchang, but we are still a newcomer with a relatively weak foundation in many winter sports compared with worldwide powers", said Gao Zhidan, deputy head of the Chinese delegation and a deputy director of the General Administration of Sport of China.
Moon joined Kim Yo Jong and other North Korean supporters Saturday in cheering for the team against Switzerland. The women suddenly stood up and erupted in synchronized chants, enthusiastically waving flags depicting the unified Korean peninsula in a light blue color. The official added that Pence does not believe that the invitation dilutes the toughness of the United States pressure campaign on North Korea. North Korea has said its nuclear weapons are not for bargaining away. "We are making sure our systems are secure and they are secure".
