North Korea's ruling communist party has adopted a resolution calling for the nation to focus more on developing cutting-edge weapons, Pyongyang's media reported Friday.

The decision came at a meeting of the Central Committee's Political Bureau of the Workers' Party of Korea to celebrate the 70th anniversary of the party's establishment and Korea's liberation from Japan's 35-year-long colonial rule, the official Korean Central News Agency said.

The North's leader Kim Jong-un attended the session held in Pyongyang on Tuesday, it said.

The North will "manufacture larger numbers of powerful, cutting-edge military hardware of its own style that are of high precision, light, unmanned and intelligent" to be prepared for modern warfare, read the resolution.

It stressed the spirit demonstrated in "conquering outer space."

The North succeeded in sending a long-range rocket into orbit in 2012. The world is concerned that the nuclear-armed country may have mastered a technology to miniaturize warheads.

The resolution said it's urgent to "step up the work of arming all the people and fortifying the whole country on a high level" to win the showdown with the United States.

It also declared a campaign to pave the way for "independent reunification" with South Korea and broaden diplomatic ties.

"We will resolutely frustrate the anti-DPRK war moves and nuclear and human rights rackets by the U.S. imperialists and the South Korean puppets," added the resolution, referring to North Korea by the acronym of its official name, the Democratic People's Republic of Korea.

"We will also develop foreign relations in a multilateral and proactive way, and strengthen international solidarity with our revolution."  (Yonhap)
