The South Korean and North Korean Olympic delegations walked together during the parade of nations at the Winter Olympics opening ceremony on Friday.

The two delegations walked out in matching uniforms, marching with the Korean unification flag. The flag was jointly carried by South Korean bobsledder Won Yun-jong and North Korean ice hockey player Hwang Chung-gum, according to The Guardian.

During the parade of nations, South Korean President Moon Jae-in shook hands with Kim Yo Jong, the sister of north Korean dictator Kim Jong-un.

North Korea's decision to participate in the Winter Olympics in Pyeongchang was considered a symbolic breakthrough amid rising nuclear tensions and a war that never officially ended. North Korea's participation in the Olympics has been sporadic, with their last winter Olympics coming in 2010 in Vancouver.

This year, they sent a small delegation, and they have a joint women's hockey team with South Korea.

According to reports from the opening ceremony, there were anti-unification protests outside of the stadium.

Additionally, impersonators dressed as US President Donald Trump and North Korean dictator Kim Jong-un showed up at the ceremony but were later kicked out.
