BEIJING, March 18 (Xinhua) -- The chief U.S. negotiator to the six-party talks Christopher Hill on Sunday evening said that all the delegations finished the denuclearization working group meeting and everyone has positive feel on that.

Hill said all the delegations will assess the work of all the working groups in the sixth round of the six-party talks on Monday.

"All sides are very positive about El Baradei's visit", said Hill.

There was a brief discussion on the HEU (highly enriched uranium) during the plenary working group meeting, but there was not any movement on the issue, Hill noted.

He said the Democratic People's Republic of Korea (DPRK) had started to prepare for the denuclearization, but clearly it has a lot of work to do beyond the 60 days.

The DPRK needs to pick up pace and set up a timetable for its work beyond the 60 days, Hill added.

Hill reiterated that the BDA issue will not be a problem and he will talk to Washington in the next couple of hours and talk with the Daniel Glaser later on Sunday night.

Glaser will not attend the six-party talks, he added.

According to Hill, the DPRK will send representative to Vienna to discuss with IAEA (International Atomic Energy Agency) on the schedule of shutting down its nuclear facilities in Yongbyon.
