Fireworks erupt as the Olympic Cauldron is lit during the Opening Ceremony of the PyeongChang 2018 Winter Olympic Games at PyeongChang Olympic Stadium on February 9, 2018 in Pyeongchang-gun, South Korea.
Mr Pence stayed seated when South and North Korean athletes marched together under a unified flag, and also skipped a dinner with the North Korean delegation.
South Koreans angry at North Korea's perceived "hijacking" of the Pyeongchang Winter Olympics have sarcastically dubbed it the "Pyongyang Games", but it seems many really are struggling to differentiate between the two places.
Kim Yo Jong shook hands with Moon at the beginning of the ceremony.
"President Moon and President Trump are completely aligned in their objective for a nuclear free Korean Peninsula", Pence said.

He left the event early to attend a pre-scheduled dinner with American athletes, according to the South Korean president's office.
The trip has the potential to become something of a coming out party - certainly for Kim Yo- jong, but also for her deeply isolated country.
The two-week Winter Olympic games will kick off with the highly anticipated Opening Ceremony.
Meanwhile, in South Korea, there was the realization of the divide between an older generation who may still dream of reconciliation and younger people who are more cynical.
Although inter-Korean talks are occurring on the sidelines of the Olympics, Pence is confident that Seoul and Tokyo "are solidly with our alliance and the need to continue and intensify economic sanctions", the official said.
