North Korea struck a pessimistic tone after the collapse of a two-day summit between Kim Jong Un and Donald Trump, hardening its stance with a warning by a top diplomat that Kim may have ¡°lost the will¡± to reach an agreement on curtailing his country¡¯s nuclear program.

During a rare news conference by North Korean officials, Foreign Minister Ri Yong Ho disputed Trump¡¯s claim that Kim had demanded a complete removal of all economic sanctions, insisting that his nation had ¡°offered a realistic proposal¡± to begin the process of denuclearization.

North Korean Vice Foreign Minister Choe Son Hui told reporters the ¡°U.S. not accepting our proposal is missing an opportunity that comes once in a thousand years.¡±
