Soldiers, tanks and other military hardware were paraded in Pyongyang in a show of strength on Saturday. Despite Beijing's key role in propping up North Korea, the Kim Jong-Un regime has repeatedly ignored warnings and sanctions from its powerful ally.

The Global Times said Trump's decision to drop the "mother of all bombs" on Afghanistan was clearly "a new gimmick in USA military deterrence" created to intimidate Kim Jong-un.
