Story highlights China dismisses calls to intervene more in North Korea

Pyongyang hails the missile test as a success

Hong Kong (CNN) China has voiced opposition to North Korea's test of a reported new ballistic missile more than 24 hours after reports of the launch emerged.

But the country shrugged off suggestions it should be doing more to intervene in the rogue state's military affairs, pinning the test down to Pyongyang's testy relations with Washington and Seoul.

North Korean state media hailed the Sunday test as a success, claiming a previously unpublicized part of the country's arsenal -- a Pukguksong-2, an intermediate-range missile -- was launched under the supervision of North Korean leader Kim Jong Un.

North Korea is prohibited from carrying out ballistic missile launches under UN Security Council resolutions aimed in part at curbing the country's development of nuclear weapons.

China's Foreign Ministry said that his country was opposed to launch activities in violation of the resolutions.
