North Korean leader Kim Jong Un capped off his 10th year in power with a speech that made more mention of tractor factories and school uniforms than nuclear weapons or the United States, according to summaries by state media on Saturday.

North Korea's main goals for 2022 will be jump starting economic development and improving people's lives as it faces a "great life-and-death struggle," Kim said in a speech on Friday at the end of the 4th Plenary Meeting of the 8th Central Committee of the Workers' Party of Korea (WPK), which began on Monday.

The meetings coincided with the 10-year anniversary of Kim effectively assuming leadership of the country after the death of his father in 2011.
