Anyway, anything more about these rumours emerged yet?
North Korea's state-run media has acknowledged the country was experiencing difficulties, lauding the direction of supreme leader Kim Jong Un but staying silent on his public absence amid rumors regarding his health.
Rodong Sinmun, the newspaper of the ruling Korean Workers' Party Central Committee, published an article Wednesday saying that the country does "have some [areas] lagging behind others so far. It is also true that we are going through hardships," as translated by the South Korea-based NK News. The report ultimately placed faith in Kim's efforts to build a "strong, self-reliant foundation" that meant "catching up with the advancing countries' level is never a matter of a distant future."
