South Korean President Yoon Suk-yeol's plans to offer economic aid in return for denuclearisation could face an early challenge amid signs of an imminent North Korean nuclear test - and such proposals have been rebuffed before, analysts say.
Yoon has warned of a "tense" security environment, citing the possible nuclear test, which U.S. and South Korean officials have said could occur as early as this month after Pyongyang broke a 2017 moratorium on long-range missile testing in March.
