Kim Kyong Jun, vice-minister of Land and Environmental Conservation, told KCNA:

"This work fully represents Kim Jong Un's outlook on the people and posterity.

It defines air-pollution prevention as an important issue in environmental conservation, while pointing out that officials who pay less attention to preventing air pollution are those lacking loyalty to the people.

I really feel remorseful. Each word and phrase of the work is vibrant with patriotism as ardent as leader Kim Jong Il.

As instructed by Kim Jong Un, I will keep the genuine outlook on the people that puts their interests above anything else and make fresh turn in the efforts for land and environmental conservation."

Jong Yong Nam, vice-chairman of the C.C., Nature Conservation Union of Korea, said:

"Kim Jong Un's work mirrors his strong will to remain faithful to Kim Jong Il's idea on land management and glorify the feats he performed to that effect.

In his lifetime, Kim Jong Il instilled in the minds of the Korean people the idea that they should devote themselves to ensuring the happiness of posterity, although they may not enjoy benefits.

As intended by the work, I will devote myself to turning the country into a land of eternal happiness for posterity under the leadership of Kim Jong Un who has embodied Kim Jong Il-style patriotism at the highest level."
