China stays neutral on N Korea
China has held back from censuring North Korea at a summit in South Korea dominated by the issue of a sunken warship.
South Korea has accused North Korea of torpedoing the Cheonan, which sank on 26 March with the loss of 46 lives.
Chinese Premier Wen Jiabao said the priority was to reduce tensions and avoid a clash over the incident.
