The U.S. State Department warned against expecting too much from the meeting.
"We do not anticipate that there will be any final resolution," said spokesman Tom Casey. "I am sure that will include a variety of topics, including some bilateral ones, but I am sure (Hill) will also use that as an opportunity to provide a readout of the discussions that he will have had previously with Kim Kye-gwan."
South Korean Foreign Ministry officials were upbeat about a potential breakthrough in talks, which stalled after North Korea said it submitted a required list of its nuclear activity and the U.S. disputed the claim.
"(There) are expectations that he will bring an answer acceptable to the U.S., given he comes way down to Singapore for talks despite the firm U.S. stance that it will have the next meeting with North Korea only to strike a deal, not to have further negotiations," the ministry official said.
