During negotiations beginning Monday in Sweden, Japan aims to get North Korea to agree to reinvestigate the fates of Japanese it abducted in the 1970s and 1980s, government sources said Saturday.

Japan is considering easing sanctions it has unilaterally imposed on North Korea, such as travel restrictions, if the reinvestigation makes a certain amount of progress, the sources said.

It will also ask North Korea to put any agreements reached during the three-day talks through Wednesday in the capital, Stockholm, in writing, they said.
