Supreme leader Kim Jong Un in his New Year address for Juche 105 (2016) said that the principle of giving priority to self-development should be maintained.

He also said that self-development alone is the road to sustaining the dignity of our country and our nation and to paving a broad avenue for the revolution and construction.

With affection, trust, dignity and pride in everything of their own, the Korean people wrought eye-opening miracles in all sectors despite the hostile forces' all sorts of toughest sanctions and blockade and pressure upon the DPRK.

The DPRK succeeded in the first H-bomb test and nuclear warhead explosion test this year when the 7th Congress of the Workers' Party of Korea was held and ranked itself among advanced nuclear powers.

It also successfully launched earth observation satellite Kwangmyongsong-4, 100 percent locally manufactured on the threshold of the Day of the Shining Star (February 16), leader Kim Jong Il's birthday.

Meanwhile, it made unprecedented achievements one after another in the fields of electric power, coal-mining, metal, machine, light industry, agriculture, construction, scientific research and sports.

The Kim Jong Thae Electric Locomotive Complex, manufactured high performance electric locomotives of new type in the self-development spirit in the wake of the production of the first underground train.

80hp tractors and other modern trucks, buses, cargo ships and solar-powered ferryboats were made in the fields of machine industry and land and marine transport. And Hwanggumhae-class multi-purpose fishing boats were built in the field of fisheries.

Scientists and technicians manufactured 250kW wind power generator, completed the technology of producing electrode for UHP electric arc furnace and developed the Korean-style mining machinery, electric motors, energy-saving transformers and CNC machines.

In the period of the 70-day campaign, hundreds of objects were completed and remodeled and went operational. The flood-hit northern parts of North Hamgyong Province were recovered in the 200-day campaign and thousands of industrial establishments overfulfilled their yearly plans.
