US and China to co-operate over North Korea


US President Barack Obama says China and the United States will work together to try and prevent further missile tests by North Korea.

In recent weeks, North Korea has carried out a hydrogen bomb test and has repeatedly test-fired missiles while making threats to the West.

Obama met Chinese President Xi Jinping on the sidelines of a nuclear summit in Washington yesterday.

Obama said both countries were keen to see a nuclear-free Korean peninsula.
