North Korean leader Kim tours weapons factories and vows to boost war readiness in face of tensions

North Korean leader Kim Jong Un toured the country's key weapons factories, including those producing artillery systems and launch vehicles for nuclear-capable ballistic missiles, and pledged to speed up efforts to advance his military's arms and war-readiness, state media said Sunday.

North Korean leader Kim Jong Un toured the country's key weapons factories, including those producing artillery systems and launch vehicles for nuclear-capable ballistic missiles, and pledged to speed up efforts to advance his military's arms and war-readiness, state media said Sunday.

Kim's three-day inspections through Saturday came as the United States and South Korea prepared for their next round of combined military exercises planned for later this month to cope with the growing North Korean threat.

Tensions on the Korean Peninsula are at their highest level in years as the pace of North Korea's missile tests and the joint U.S.-South Korea military drills, which Kim portrays as invasion rehearsals, have both intensified in a tit-for-tat cycle.

Some experts say Kim's tour of the weapons factories could also be related to possible military cooperation with Moscow that may involve North Korean supplies of artillery and other ammunition as Russian President Vladimir Putin reaches out to other countries for support in the war in Ukraine.

During Kim's visit to an unspecified factory producing large-calibre artillery systems, he stressed the factory's "important responsibilities and tasks in perfecting (the North's) war readiness," North Korea's official Korean Central News Agency said.

Kim praised the factory's efforts to employ "scientific and technological measures" to improve the quality of shells, reduce processing times for propellent tubes and increase manufacturing speed, but also called for the need to develop and produce new types of shells, KCNA said.

At another factory manufacturing launcher trucks designed to transport and fire ballistic missiles, Kim said increasing the supply of the vehicles is a top priority for the military and complimented workers for establishing a "solid foundation" for production.
