U.S. considering various options for successful talks with N. Korea: Seoul's Unification Minister

North Korea may have sneered at the possibility of holding further talks with the U.S., but South Korea's unification minister is remaining hopeful.
After a luncheon with U.S. Special Representative for North Korea Policy, Stephen Biegun, in Washington Monday... Kim Yeon-chul said the U.S. is considering various options to hold successful denuclearization talks with North Korea.
Kim didn't elaborate on what those options might be, citing the sensitivity of the issue.
This is Kim's first trip to the U.S. since becoming minister in April.
