Prime Minister Junichiro Koizumi might express concern over the harassment of Korean residents in Japan that followed North Korea's admission in 2002 that it had abducted Japanese nationals in the 1970s and 1980s, government sources said Thursday.

By expressing such concerns during his Saturday meeting with North Korean leader Kim Jong Il, Koizumi apparently hopes to show that he takes the matter seriously. The move is an apparent attempt to soften Pyongyang's stance on pending bilateral issues.

He might also tell Kim that if the family members of five repatriated abductees are allowed to leave North Korea for Japan, the government would not invoke an envisioned law that would allow it to ban the port entry of certain ships, particularly those from North Korea, the sources said.
