The President pioneered a new road of an independent national economy from the first period of building a new country after the liberation of the country. In the postwar period, he set forth a policy and tasks for laying foundations of industrialization in the period of a five-year plan and energetically led the effort for its accomplishment.

On July 29, Juche 42 (1953), two days after the cease-fire, he visited the then Hwanghae Iron Works and said that priority should be given to heavy industry in the rehabilitation of national economy and the open-hearth furnace should be the first target in the reconstruction of the works to produce steel necessary for the rehabilitation of the economy.

Inspired by his field guidance, the workers of the factory replaced the destroyed 50-ton open-hearth furnace with a 100-ton one in spite of the obstructionists' moves.

The campaign for the postwar rehabilitation and construction was expanded all over the country under his wise leadership.

The then Kangson Steel Plant finished the rebuilding of electric furnace No. 2 in 40 days after the cease-fire and turned out the first molten iron while the then Songjin Steel Plant started the steel production less than two months after the cease-fire.

Huichon, Rakwon, Ryongsong and other major machine plants manufactured lathes, presses, 8-meter turning lathes, large machine tools and vehicles such as motorcar, tractor and bulldozer. The chemical industry base in Hungnam started the fertilizer output.

The socialist industrialization was carried out in the country in only fourteen years.

Monumental edifices erected in different parts of the country are also associated with his immortal feats.

The foundations of the socialist independent national economy have been further consolidated under the Songun revolutionary leadership of General Secretary Kim Jong Il.
