(CNN) Representatives of North Korea, South Korea and the United States are set to meet in Finland for talks on denuclearization, according to South Korean and Finnish officials.

The North Korea talks in Finland will include American representatives who are not government officials, said Kimmo Lahdevirta, an official at the Finland foreign ministry. The US does not have a diplomatic presence in North Korea.

South Korea's Foreign Ministry told CNN that former officials and private experts from South Korea would be at the "second-tier" talks on denuclearization. The ministry suggested the US would also be represented in some way, without giving details.

Lahdevirta described the meeting as a "track 1.5 academic meeting ... involving representatives from North Korea, South Korea and the US."

So-called "track 1.5 talks" bring together a mixture of current government officials and nongovernmental experts.
