No result was achieved in the fourth round of six-party talks on Wednesday, the second day of the event, said Russian delegation head Alexander Alexeyev.    

"There are still substantial and even conceptual differences between North Korea and the US," Alexeyev, deputy foreign minister of Russia, was quoted by the Interfax as saying.

It is reported that the North Korean and the US delegations will hold another meeting this morning. Alexeyev said that the outcome of bilateral consultations will influence the result of six-party talks to a large extent.

He said that all the six parties remain cautiously optimistic about the current round of talks and continue to work together to narrow the differences between North Korea and the US.
