Foreign Minister Yang Jiechi told his South Korean and Japanese counterparts that China was "concerned and worried" about the potential impact of North Korea's planned rocket launch this month, state media said on Sunday. China hoped all parties would "keep calm and exercise restraint" and resolve differences over the planned launch through dialogue, the official Xinhua news agency quoted Yang as telling the South Korean and Japanese ministers. Yang said China would "keep communication and coordination with all sides" to promote six-nation talks on ending North Korea's nuclear weapons programme.
