The official characterized the moves as China's effort to "reduce the time to react to a North Korea contingency," as quoted by the broadcaster.
Media reported earlier on Thursday that North Korea's leader Kim Jong-un warned the United States through the state media of a "super-mighty preemptive strike."
Tensions on the Korean peninsula have risen over the recent month in the wake of Pyongyang's nuclear tests and ballistic missile launches conducted in violation of the UN Security Council's resolutions. North Korea reportedly carried out the most recent missile launch early on Sunday however it was unsuccessful according to South Korea's defense officials.
In response to the tensions around North Korea, the United States sent the USS Carl Vinson aircraft carrier and its strike group including two destroyers and a cruiser to the Korean Peninsula. On April 14, media reported that US President Donald Trump might order a strike against North Korea if Pyongyang decided to carry out another nuclear weapon test.
On Friday, Chinese Foreign Minister Wang Yi urged both the United States and North Korea to refrain from the potentially catastrophic conflict.
