The city named Samjiyon is envisaged as a "socialist utopia" with new apartments, hotels, a ski resort and commercial, cultural and medical facilities.
KCNA said it could accommodate 4,000 families and has 380 blocks of public and industrial buildings in "hundreds of hectares."
The city is one of the largest economic initiatives Kim has launched as part of his drive for a "self-reliant economy, but its construction was delayed chiefly due to shortages in construction materials and labor as a result of sanctions imposed to curb Pyongyang@@@s nuclear program.
