North Korea will hold a rare ruling party congress in January where leader Kim Jong Un will announce a new five-year plan to develop the country's dismal economy ravaged by U.S.-led sanctions and the coronavirus pandemic, state media said Thursday.

The plans were confirmed Wednesday during a plenary meeting of the Workers' Party's decision-making Central Committee where Kim acknowledged economic shortcomings caused by ''unexpected and inevitable challenges in various aspects and the situation in the region surrounding the Korean Peninsula.''

The report by Pyongyang's official Korean Central News Agency didn't directly mention nuclear diplomacy with the United States, which has stalled over disagreements in exchanging sanctions relief and denuclearization steps.

The Workers' Party last convened for a full congress in 2016, which was its first in 36 years, where Kim announced his initial five-year national development plan, which included goals for improving power supply and increasing agricultural and manufacturing production.

Entering the plan's final year, Kim during the Central Committee's last plenary meeting in December declared a ''frontal breakthrough'' against sanctions while urging his nation to stay resilient in the struggle for economic self-reliance.

But experts say the COVID-19 crisis has clearly derailed some of Kim's major economic goals after North Korea imposed a lockdown that significantly reduced trade with China -- its major ally and economic lifeline -- and likely hampered its ability to mobilize its workforce.

It's also possible Kim could use the party congress, which would take place after the U.S. presidential election in November, to announce a new foreign policy approach toward the United States and rival South Korea.

Kim's economic setbacks have left him with nothing to show for his high-stakes summitry with President Donald Trump, whom he first met in June 2018 in Singapore, where they issued an aspirational statement on a nuclear-free Korean Peninsula without describing when and how it would occur.

Their diplomacy deteriorated last year in Vietnam, after their second meeting, when the Americans rejected North Korea's demands for major sanctions relief in exchange for a partial surrender of its nuclear capabilities.

The North has recently said it has no immediate intent to resume talks with Washington, vowing not to gift Trump with meetings he could boast as foreign policy achievements unless it gets something substantial in return.

Some experts say the North would likely avoid serious negotiations with the United States before the election as it wouldn't want to make any major concessions when there's a chance U.S. leadership could change. (AP)
