The event took place at the Mansudae Assembly Hall, where Kim Jong Un reshuffled North Korea’s highest decision-making body last month.
The presumed dead – North Korean leader – Kim Jong Un recently made his public appearance after it was widely speculated that he was either dead or seriously unwell.
Russian Ambassador Alexander Matsegora and North Korean foreign minister Ri Son Gwon held a brief sit-down following the ceremony.
No reporting by state media on the recent missile test launches featuring Kim Jong-un further fueled speculations.
North Korean media on Saturday broadcast video of Kim during a ribbon-cutting ceremony for the inauguration of a fertiliser plant.
