No deal was reached Sunday during a tense day of six-nation talks
aimed at ending North Korea's nuclear programme, and discussions
will continue into the working week, the chief Japanese envoy
said.
"I think the situation still remains tough. Tomorrow it will
become clearer which way it is going, whether the discussions
are heading towards a settlement or not," Kenichiro Sasae
told reporters.
The latest round of talks -- which began in 2003 and involve
host China, the two Koreas, the United States, Japan and Russia
-- began on Thursday on a positive note, with China circulating
a draft accord on a potential deal.
The plan calls for Pyongyang to begin taking steps towards ending
its nuclear programme in return for economic incentives, but has
snagged on what Sasae said earlier Sunday were North Korea's "excessive"
demands for energy aid.
Sasae said following the end of Sunday's talks that the day's
events had been held in a more tense atmosphere than the previous
day, and that energy remained one of the biggest sticking points.
"It is indeed one of the biggest issues," he said,
when asked about the debate over energy.
North Korea, apparently emboldened by its October detonation
of a nuclear device, has demanded two million tonnes of fuel oil
and other inducements, Japanese press have reported.
That would be four times as much fuel oil as offered under a
now-defunct 1994 disarmament deal.
