South Korea's new president Lee Jae-myung

New elected South Korean President Lee Jae-myung vowed to reach out to the North and heal wounds as he took office Wednesday, after winning a snap election triggered by his predecessor's disastrous martial law declaration. Lee scored a thumping victory over conservative Kim Moon-soo of the ex-president's former party, securing 49.4 percent of the vote, ahead of the 41.2 percent for Kim.
