Pyongyang: North Korea announced on Wednesday that it has successfully carried out its first hydrogen bomb test.
The "total success" of the test, which took place at 10.00 a.m., has turned North Korea into a real nuclear-armed country with hydrogen bombs, Xinhua reported.
Earlier in the day, the China Earthquake Network Centre said a 4.9-magnitude earthquake jolted North Korea at a depth of zero km.
Meanwhile, the US Geological Survey reported an earthquake was detected in North Korea with a magnitude of 5.1 and at a depth of 10 km.
China has always pushed for the de nuclearisation of the Korean Peninsula, maintaining that all relevant parties should refrain from unilateral moves detrimental to regional peace and stability.
