North Korea celebrated the birthday of its late founder Kim Il-sung on Sunday,... refraining from any provocative acts or words,... ahead of its summits with South Korea and the United States. <br /> The calm celebration is in stark contrast with the past when the North conducted missile tests marking the occasion in 2016,... and a large-scale military parade last year. <br />Kim Il-sung's birthday,... also called the Day of the Sun,... is North Korea's largest national holiday. <br />
