China put a brave face on six-way talks aimed at solving the North Korean nuclear crisis on Saturday but said much work remained to be done.North Korea, the US, South Korea, Japan, China and Russia agreed to more working-level discussions and a third round of full-fledged six-party talks by the end of June, but little else when their three days of second-tier discussions in Beijing ended on Friday.‘‘There is still a long way to go to settle the Korean nuclear issue,’’ Xinhua quoted Chinese Vice Foreign Minister Dai Bingguo as telling delegates on Saturday. North Korea, in its first reaction to the talks, blamed the US for the lack of progress but said Pyongyang would continue to negotiate. The North Korean Foreign Ministry said a majority at the talks had supported Pyongyang’s ‘‘reward for freeze’’ proposal.
