China was resolutely opposed to the nuclear test by the Democratic People's Republic of Korea (DPRK), the Foreign Ministry said in a statement Monday.

According to a report by the official Korean Central News Agency (KCNA), the DPRK announced it successfully conducted an underground nuclear test on Monday.

"The DPRK ignored universal opposition of the international community and once more conducted the nuclear test. The Chinese government is resolutely opposed to it," the statement said.

It has been the firm and consistent stance of the Chinese government to achieve non-nuclearization on the Korean Peninsula and oppose proliferation of nuclear weapons in an effort to maintain peace and stability in northeast Asia, the statement stressed.

The statement voiced a strong demand that the DPRK live up to its commitment to non-nuclearization on the Korean Peninsula, stop any activity that might worsen the situation and return to the track of the six-party talks.

The statement noted that maintaining peace and stability in northeast Asia region conformed to the common interests of all parties concerned, called for a calm response from all parties concerned and urged them to pursue peaceful resolution of the issue through consultation and dialogue.

China would continue its unremitting efforts to this end, the statement added.

According to a statement released by the KCNA, the DPRK government said the test was "part of [its] measures to bolster its nuclear deterrent for self-defense in every way, as requested by its scientists and technicians."

The brief statement gave no details about the test, including its location.

Officials in the Republic of Korea said earlier Monday that an "artificial earthquake" was detected near the northeastern town of Kilju, about 10 km from the site where the DPRK staged its first nuclear test in October 2006.
