North Korea made a concerted effort to build up the personality cult of its leader Kim Jong-un through literary and artistic works ahead of the recently closed congress of the Workers' Party of Korea, an examination of North Korean media reports showed Tuesday.

In media reports released last week, the North's Korean Central News Agency said the country's youth and students created some 1,200 literary works during the 70-day campaign of loyalty that preceded the four-day party congress that ended on May 9.

Local North Korean watchers who checked the reclusive country's media said moves to idolize Kim, who has been in power since late 2011, sped up ahead of the landmark event. They said such actions are in line with the country's past practice of making its leader into a glorified being. Kim was named the new chairman of the WPK at the congress.

Pyongyang already completed a 70-day campaign of loyalty, a scheme to mobilize its people to work harder on state construction and other projects.

According to the KCNA report, a lot of literary works related to the North Korean leader were produced by young people.

For example, the news agency claimed a youth group called the Paektusan Hero Youth Stormers released a literary production named "We are the heroes of youth powerful country" in which many literary works praised the North Korean leader with "great honor and deep trust from the people."

In the literary works, university students across the country pledged to become heroes of the country to create miracles on their way to constructing a powerful socialist state by uniting around leader Kim Jong-un.

Another North Korean media outlet, Airang-Meari, claimed on May 5 that a theatrical play was produced glorifying Kim Jong-un. The play was titled "Hyolmaek," or blood vessel, and was produced by the North's state theatrical troupe. It showed the "honorable Marshal Kim Jong-un's sublime will for the construction of a great prosperous country on the ground."

In addition, the North's Central TV Station introduced an epic poem idolizing Kim Jong-un as well as his grandfather Kim Il-sung and his late father Kim Jong-il.

The poetry was introduced on the opening day of the WPK congress on May 6 in a move to elevate Kim Jong-un to the level of his two predecessors.

In his report to the party congress, Kim Jong-un urged the nation to create literary and artistic works to glorify the great revolutionary history and immortal achievements of the deceased leaders. (Yonhap)
