North Korea criticises China's 'reckless' remarks on nuclear dispute

North Korea has issued a rare direct criticism of China through a commentary saying its "reckless remarks" on Pyongyang's nuclear programme are testing its patience and could trigger unspecified "grave" consequences.

China, North Korea's largest trading partner and main benefactor, has been urging the North to stop nuclear and missile activities amid US pressure to use its leverage to resolve the nuclear stand-off.
