The six parties involved in the Korean nuclear issue would make their final attempt to clinch a deal as the talks entered fifth day on Monday, with energy aid still a focus of the negotiations.
"It is the last day of the talks, let's see how it goes," said chief US negotiator Christopher Hill. "We put everything on the table, it's up to DPRK (the Democratic People's Republic of Korea)," he said.
The Republic of Korea (ROK) chief negotiator Chun Yung Woo said: "The sky in Beijing is very clear, but the prospect for the six-party talks is unclear."
At a chief delegates' meeting on Sunday, the DPRK agreed with other parties to conclude the talks on Monday. "This shows the DPRK has the will to achieve results today," said Chun.
But whether the talks will conclude on Monday depends on what the attitude the DPRK will take, Chun added.
Envoys from host China, the DPRK, the US, the ROK, Japan and Russia reconvened the talks on Thursday in Beijing in the wake of a 48-day recess.
But the talks got blocked by the energy aid to the DPRK after the negotiators held consultations on a Chinese draft, which involves the moves the DPRK will take to abandon its nuclear programme in return for economic aid and security guarantee.
The draft reportedly proposes halting within two months the work at nuclear sites in the DPRK, including the Yongbyon reactor, and supplying Pyongyang with alternative energy sources.
