China's Foreign Ministry has expressed 'regret' at a long-range rocket launch by North Korea.
Beijing called on all sides to act cautiously and refrain from taking steps that might further raise tensions on the Korean peninsula.
Ministry spokeswoman Hua Chunying said: "China expresses regret that North Korea, in spite of the pervasive opposition of the international community, insisted on using ballistic missile technology to carry out a launch."
She added that dialogue is the only way to ensure lasting peace and stability in the region.
North Korea's state television said a long-range rocket launch on Sunday, ordered by leader Kim Jong-Un to put a satellite into space, was a "complete success".
The announcer said the satellite, called 'Kwangmyongsong-4', is orbiting the earth every 94 minutes and the North would continue to launch satellites in future.
The rocket was fired from a launch pad on North Korea's west coast between 9.30am and 9.35am local time on a southern trajectory over the East China Sea.
Debris from the rocket crashed back to earth around 155 miles off the south-west coast of the Korean Peninsula around 14 minutes after take-off.
Meanwhile United Nations Secretary-General Ban Ki-moon strongly condemned the launch and urged Pyongyang to "halt its provocative actions."
It is deeply deplorable that (North Korea) has conducted a launch using ballistic missile technology in violation of relevant Security Council resolutions on 6 February 2016 despite the united plea of the international community against such an act.
South Korean President Park Geun-hye described North Korea's long-range rocket launch on Sunday as "an unforgivable act of provocation" and called on the UN Security Council to swiftly adopt strong sanctions.
Park said the North was trying to make advances in its missile capability only to sustain its regime.
North Korea's state television said there will be a special broadcast about Pyongyang's rocket launch at noon (local time).
The US has strongly condemned North Korea for launching a long-range rocket.
In a statement from the White House, National Security Advisor Susan Rice said the move "represents yet another destabilising and provocative action and is a flagrant violation of multiple United Nations Security Council resolutions."
North Korea’s missile and nuclear weapons programs represent serious threats to our interests--including the security of some of our closest allies--and undermine peace and security in the broader region.
We condemn today's launch and North Korea's determination to prioritize its missile and nuclear weapons programs over the well-being of its people, whose struggles only intensify with North Korea’s diversion of scarce resources to such destabilising activities.
The United States is fully committed to the security of our allies in the region, and we will take all necessary steps to defend ourselves and our allies and respond to North Korean provocations.
We call upon the international community to stand together and demonstrate to North Korea that its reckless actions must have serious consequences.
