PYONGYANG - Kim Jong-un, the top leader of the Democratic People's Republic of Korea (DPRK), visited an important tank factory, the official Korean Central News Agency (KCNA) reported Sunday.

Kim, general secretary of the Workers' Party of Korea and president of the State Affairs, stressed that replacing the armored weapons of the last century with latest tanks and armored vehicles is the most important issue in the building of armed forces and modernization of the army, the KCNA reported.

The Academy of Defense Sciences and the workers and technicians of the factory have made remarkable progress and success in developing tanks and armored weapons and improving their combat performance, said the KCNA.

The traveling and different mobile characteristics of tanks were improved through the integrated power transmission device. And the new-type active protection complex, passive protection means and the electronics warfare complex were updated in a more innovative way. All these successes mean great progress in the core technology of DPRK tanks, Kim was quoted as saying.

On Saturday, KCNA said the US arms buildup on the Korean Peninsula and in the region will be an unwise option to further increase the uncertainty of US mainland security.

The warning was issued by an unnamed military commentator quoted by the KCNA.

The interceptor drill simulating the so-called intercontinental ballistic missile attack of an enemy state, conducted recently at the Fort Greely military base in Alaska, is a military action of "an offensive nature that made a nuclear war with the DPRK a fait accompli," the commentator was quoted as saying.

If the United States does not seek a nuclear war with the DPRK, the DPRK strategic nuclear force targeting the US mainland will not happen, and there is no need to talk about "interception," the commentator was quoted as saying.

The recent US moves of assembling strategic bombers and stealth fighters in the Korean Peninsula region prove that "the US arms buildup to raise the level of war readiness in all aspects of attack and defense has entered the stage of mastering practical action, far beyond the level of demonstration," the commentator was quoted as saying.
