North Korean leader Kim Jong Un set forth new policies to increase the nation's nuclear deterrence at a meeting of military leaders, state news agency KCNA reported Sunday, EDNew.net reports citing CNN.

The meeting is the North Korean leader's first known public appearance since he attended a ceremony marking the opening of a fertilizer factory earlier this month following global speculation about his health.

Kim presided over a meeting of the Workers' Party of Korea Central Military Commission (CMC), according to KCNA.

KCNA didn't report details but said "crucial measures for considerably increasing the firepower strike ability of the artillery pieces of the Korean People's Army" were taken at the meeting, as well as actions "putting the strategic armed forces on a high alert operation."

At the meeting, Kim signed seven orders, KCNA reported. The orders concerned "enhancing" the responsibility and roles of major military educational institutions, reorganizing the military command system "to meet the mission and duty of the security institutions" and promoting the military ranks of commanding officers, KCNA said.

The meeting also "reviewed and analyzed a series of drawbacks in the military and political activities of the overall armed forces of the DPRK" and discussed "methodological issues for overcoming them and bringing about drastic improvement," according to KCNA.

The meeting "served as a historic turning point of great significance in increasing the capabilities of the revolutionary armed forces," according to KCNA.
