At the opening ceremony of the 2018 PyeongChang Winter Olympics, North and South Korea have decided to march out together under a Korean Peninsula flag.
It's been more than a decade since the two sides last competed jointly, and the first time at an Olympics.
South Korea's Vice Minister for Unification, Chun Hae-sung, made the announcement.
"South and North Korea will march together under one flag in the opening ceremony of the PyeongChang Winter Olympics, and field a combined women's ice hockey team."
"North Korea will send a 230-member cheering squad, and they will cheer events at the PyeongChang Winter Olympics, and perform a joint cheering event with South Korea."
North Korea says it will also send a 150-member delegation to the Paralympics.
The proposed North-South women's ice hockey team is generating controversy, though.
Traditionally a stronger sporting force, the coach of the South Korean team says players have expressed fears they may lose their places.
The breakthrough comes after more than a week of talks in the village of Panmunjom (pan-moon-JOM), in the Demilitarised Zone.
The delegations agreed to prioritise dialogue over action, and to keep the lines of communication open by holding future meetings.
The issue of denuclearisation of the Korean Peninsula however, was swiftly shut down by the North.
The nuclear arsenal is a sticking point in international relations, too.
At a summit in Vancouver, Canada, US Secretary of State Rex Tillerson warned the isolated nation it faces military action if it does not negotiate over its weapons.
Echoing this, Japan's Foreign Minister Taro Kono has cautioned nations to treat with scepticism North Korea's newfound cooperativeness.
