The chief US envoy at six-party talks on North Korea's nuclear program says negotiators hope to agree on a "roadmap" specifying disarmament measures to be taken by the end of the year.
Assistant Secretary of State Christopher Hill said in Beijing on Thursday the parties expect to issue a statement on the matter Friday.
North Korea agreed last February to abandon its nuclear program in exchange for fuel and political concessions. It has already shut down its main nuclear facility at Yongbyon.
The six-party talks include the United States, North and South Korea, Japan, China and Russia.
This latest round of negotiations in Beijing was expected to focus on how North Korea would verifiably and completely disable its reactor at Yongbyon, and to set a timetable for the disclosure of all the country's nuclear activities. The talks are scheduled to end Sunday.
North Korea tested a nuclear weapon last year.
