Japanese negotiator Kenichiro Sasae on Thursday pledged to make all efforts to push forward the six-party talks process.
He said no gathering was arranged for the heads of the six parties on Thursday, so that they could focus on one-to-one talks to make progress.
The Japanese delegation would hold talks with the US and China separately, he said.
The fresh six-party talks started Monday after a 13-month suspension, involving China, North and South Korea, the US, Japan and Russia.
