North Korean leader Kim Jong Un admitted that his economic development plans have failed as he opened the nation’s first full ruling party congress in five years, state media reported Wednesday. In an opening speech at the congress that began Tuesday, Kim said that ‘almost all sectors fell a long way short of the set objectives’ under a previous five-year development plan established at the 2016 congress, according to the North’s official Korean Central News Agency. 36-Year-old Kim is holding the congress, which is expected to last a few days, amid what may be the toughest challenge of his nine-year rule and what he has called ‘multiple crises.’
