Russian top negotiator Alexander Losyukov to the six-party talks on the Korean Peninsular nuclear issue said in Beijing on Thursday that all the parties should adopt an "optimistic attitude" in addressing the possible problems that may erupt in the meeting.

"The six-party talks have made some progresses but facts have shown that there have been various problems in different phases of the talks," Losyukov said to reporters at the doorway on his leaving the hotel on Thursday morning.

"All the parties concerned should not lose heart, but rather, adopt an optimistic attitude to address the problems," he said.

Losyukov noted that an assessment should be made to evaluate the implementation of the agreements that have been reached.

He hoped that all the six parties can make a new timetable during the upcoming talks and urged concerted efforts to push forward the talks in line with the timetable.

Losyukov said he will meet with some delegations ahead of the start of the meeting on Thursday afternoon but did not specify the names of the delegations.

Losyukov said Wednesday he was "cautiously optimistic" about the upcoming second session of the sixth round of the six-party talks on the Korean Peninsular nuclear issue upon his arrival in Beijing.

The second phase of the sixth round of the six-party talks on the Korean Peninsula nuclear issue is scheduled to run from September 27 to 30.

The six-party talks, initiated in 2003, involved China, North and South Korea, the US, Russia and Japan.

In a session of the six-party talks held in July, envoys agreed to meet in Beijing in September to hear working group reports and work out a road map for the implementation of the general consensus reached in July.
