SEOUL, Jan. 12 -- South Korean President Park Geun-hye urged the Democratic People's Republic of Korea (DPRK) Monday to respond to Seoul's dialogue offer "without any hesitation."

The two Koreas should open a door of unification together by discussing various issues, including the "fundamental resolution" of Korean families separated during the 1950-53 Korean War, Park said in her New Year's press conference.

Given the old age of those separated families, the reunion issue can not be delayed, Park said, asking the DPRK to be open- minded in talking about the holding of the reunion event around the Lunar New Year's holiday that falls in mid-February this year.
