President Kim Il Sung put forward a revolutionary line to simultaneously and dynamically push ahead the economic construction and defence building at the 5^th Plenary Meeting of the 4^th Central Committee of the Workers’ Party of Korea in 1962 in order to hasten the socialist construction with success while reliably defending the revolutionary gains from aggression of the imperialists.

The revolutionary slogan Rifle in one hand and hammer or sickle in the other! contains both principled demand and main content of the WPK’s line.

By thoroughly adhering to the line of carrying out economic construction and defence building simultaneously, the WPK not only made full preparedness to cope with war but laid solid foundations for the durable and viable independent economy capable of satisfying material needs of the country even in any situations.
