moon said on Wednesday there were enough favourable conditions to expect the talks to resume in July and called on Pyongyang to announce a firm date. Ban cited in particular recent contacts by U.S. and North Korean officials, which he said helped them understand each other's position better. China also encouraged more of such contacts. "We hope all parties concerned can emit more goodwill and emit more positive information to create favourable conditions for the early resumption of the six-party talks," Foreign Ministry Spokesman Liu Jianchao told a news conference. But such optimism is not shared by Japan and some analysts, who say there is little to support the view. North Korea is believed to be engaged in the spread of its nuclear capabilities, including the provision of the technology to Iran, according to a recent intelligence report obtained by Reuters in Vienna from a non-U.S. diplomat.
