Kim Jong Un called for increased missile production in a visit to a weapons factory on Saturday, underscoring his focus on weapons development two days before a summit with China’s president.

During a visit to the unspecified factory, the North Korean leader emphasized the need to boost capacity in line with the Korean People’s Army’s shifting combat organization and operational groupings, the ruling party newspaper Rodong Sinmun reported Sunday.
