North and South Korea have agreed to march together under a single "unified Korea" flag at next month's Winter Olympics in the South.
They also agreed to field a joint women's ice hockey team in rare talks at the truce village of Panmunjom.
These are the first high-level talks between the countries in more than two years.
It marks a thaw in relations that began in the new year when North Korea offered to send a team to the games.
The games will take place between 9 and 25 February in Pyeongchang in South Korea.
What will happen?
If the plans are realised, a hundreds-strong North Korean delegation - including 230 cheerleaders, 140 orchestral musicians and 30 taekwondo athletes - could cross into the South via the land border to attend the Winter Olympics.
It will mean the opening of the cross border road for the first time in almost two years.
The two countries have also agreed to field a joint team for the sport of women's ice hockey. It would be the first time athletes from both Koreas have competed together in the same team at an Olympic Games.
The North has also agreed to send a smaller, 150-member delegation to the Paralympics in March.
The agreement will have to be approved by the International Olympic Committee (IOC) meeting in Lausanne, Switzerland, on Saturday, because North Korea has missed registration deadlines or failed to qualify.
South Korea will also need to find ways to host the North Korean delegation without violating UN Security Council sanctions outlawing cash transfers to Pyongyang and blacklisting certain senior North officials.
What has the reaction been?
South Korea's hockey coach and conservative newspapers have expressed concern about the prospect of a united hockey team, saying it could damage South Korea's chances of winning a medal.
Tens of thousands of people are said to have signed online petitions urging President Moon Jae-in to scrap the plan.
But the liberal leader told South Korean Olympic athletes on Wednesday that the North's participation in the Games would help improve inter-Korean relations.
Japan has viewed the latest detente with suspicion, with Foreign Minister Taro Kono saying the world should not be blinded by Pyongyang's recent "charm offensive".
"It is not the time to ease pressure or to reward North Korea," Mr Kono said, according to Reuters news agency. "The fact that North Korea is engaging in dialogue could be interpreted as proof that the sanctions are working.
