North Korean leader Kim Jong Un said his five-year economic plan had failed to meet its goals “on almost every sector” as he kicked off a congress of the ruling Workers’ Party, state media KCNA reported on Wednesday. The rare political gathering, which Kim last hosted in 2016, has drawn international attention as he is expected to unveil a new five-year economic plan and address inter-Korean ties and foreign policy. The congress, attended by 4,750 delegates and 2,000 spectators, comes just two weeks before U.S. President-elect Joe Biden takes office. In his opening speech, Kim said the country had achieved a “miraculous victory” by bolstering its power and global prestige since the last meeting, referring to military advances that culminated in successful tests in 2017 of intercontinental ballistic missiles capable of striking the U.S. mainland and a series of meetings with U.S. President Donald Trump. But the five-year economic strategy he set forth in 2016 had failed to deliver, he said, urging North Korea’s greater self-reliance. “The strategy was due last year but it tremendously fell short of goals on almost every sector,” Kim said, according to KCNA. In his 2016 plan, Kim called for accelerating economic growth and expanding domestic sources of energy, including nuclear power, to boost electricity supplies. He also underscored the “byungjin” policy of parallel development of nuclear weapons and the economy.
