"Today the Democratic People's Republic of Korea, regardless of universal opposition from the international community, conducted another nuclear test, to which the Chinese government is firmly opposed," said the statement.
The DPRK state-run television reported earlier Friday that the country has conducted a nuclear warhead explosion test. It is Pyongyang's fifth nuclear test, and comes eight months after the last one.
"We strongly urge the DPRK side to honor the commitment to denuclearization, abide by the relevant UN security council resolutions and halt any moves that could aggravate the situations," according to the statement.
