North and South Korea have opened their first official talks in two years at a border village "without argument", the South said.
The meeting took place in Pammunjon, where the armistice was signed in the 1950-53 Korean War.
It occurred hours after US President Barack Obama and Chinese leader Xi Jinping agreed at a summit that the North had to abandon its nuclear programme.
The hour-long morning session appeared to pave the way for ministerial-level discussions next Wednesday.
Such a meeting would be the first such encounter in more than six years.
A spokesman for the South's Unification Ministry, said the two sides discussed technical issues for the ministerial meeting, including the venue and size of delegations.
"After the morning meeting, we both agreed to keep discussing," Kim Hyung-suk told reporters at the ministry in Seoul.
"And the atmosphere of today’s meeting, as both South and North Korea have come to the meeting table after some time...was such that the talks have gone smoothly without any argument."
There was no immediate comment on the talks from the North.
Before the talks got under way, officials said they would focus on normalising commercial projects, including the Kaesong Industrial Zone just inside North Korea, closed in early April, and reuniting families still separated 60 years after the war.
North Korea's overture to hold discussions reversed months of bellicose rhetoric after the United Nations imposed toughened sanctions against the North in response to its third nuclear test in February.
The North also reopened a Red Cross hotline with South Korea last week.
