US says working with China to rein in North Korea

The US says it is working hard with China to persuade it to back a strong response to North Korea over its rocket launch.

US State Department spokesperson Victoria Nuland said Washington is working with the six-party partners and UN Security Council members on such an effort

China is a member in both groupings.

The US has condemned Pyongyang's launch on Wednesday

It also called on the new North Korean leader Kim Jong-Un to focus on feeding the people of his isolated state instead of developing missile technology.

But Washington has warned that Pyongyang must face the consequences for violating UN resolutions by firing off its long-range rocket.
