North Korea has accepted an offer to attend high-level talks next week, South Korean officials have said.
The meeting, on 9 January, will focus on finding a way for North Korean athletes to attend the Winter Olympic Games in South Korea in February.
North Korean leader Kim Jong-un said this week that sending a delegation to the Games would be "a good opportunity to show unity" among North Koreans.
The meeting is expected to be held at Panmunjom, on the border.
The so-called peace village, in the heavily guarded demilitarised zone (DMZ), is where the two sides have historically held talks.
According to an official from South Korea's presidential office, the meeting's priority will be the Pyeongchang Winter Games.
However, he told South Korea's Yonhap news agency that he believed there would also "be discussions related to improving South-North ties after the North's participation in the Olympics becomes final".
These will be the first high-level talks the both Koreas have had since December 2015. It is not yet clear who will be attending.
South Korea's President Moon Jae-in has previously said he sees the Winter Olympics as a "groundbreaking chance" to improve relations between the Koreas, two countries still technically at war.
Earlier this week, in a small sign of progress, North Korea restored a telephone hotline at their mutual border, to enable the first contact about talks to be made.
However, the South Korean Unification Ministry official told AFP that the acceptance of the invitation to talks was sent by fax on Friday morning.
"The two sides decided to discuss working-level issues for the talks by exchanging documents," Baik Tae-hyun, a spokesman of Seoul's unification ministry, told Yonhap.
'Greatest threat to Japan since WW2'
The tentative moves towards the Olympic appearance come after months of escalating rhetoric from North Korea and the US.
The leaders of both countries have each threatened the other with nuclear annihilation.
North Korea has also infuriated the world with its repeated nuclear tests and missile launches, which have resulted in tightened international sanctions.
As part of efforts to smooth the path to the Olympics, the US has agreed to a request from South Korea to suspend joint military operations, scheduled to take place during the Games.
North Korea despises the drills, which it sees as invasion preparations.
US Defence Secretary James Mattis said the delay was "a practical matter" – part of "the normal give and take", and the drills would be conducted after the Paralympics finished on 19 March.
Japan added on Friday that the decision to delay drills was "not designed to compromise the increased pressure on North Korea".
Japan's Chief Cabinet Secretary Yoshihide Suga said that Tokyo, Washington and Seoul remained were still determined to "increase pressure" on North Korea.
Japanese Prime Minister Shinzo Abe on Thursday highlighted the increasing threat posed by North Korea.
"It is not an exaggeration to say the security environment surrounding Japan is at its severest since the Second World War", he said.
"By raising pressure on North Korea together with the international community, I intend to do my utmost to solve [its] nuclear, missiles and abduction issues."
