Washington urged to 'play constructive role' on DPRK

With US Secretary of State John Kerry set to arrive in Beijing, Foreign Ministry spokeswoman Hua Chunying said at a news briefing in the capital on Tuesday that US officials must "play a constructive role ... instead of pointing fingers at others".

Hua was responding to a question about recent remarks United States officials made on the Korean Peninsula nuclear issue.

"Many of these remarks were obviously irresponsible," she said.
