SEOUL — South Korea’s president-elect, Park Geun-hye, called for national reconciliation Thursday and met with foreign envoys in Seoul, a day after she was elected the country’s first female leader in a close contest that reflected generational and regional divides and growing unease about North Korea’s military threat.

Park, 60, the daughter of South Korea’s longest-ruling dictator, won 51.6 percent of votes cast Wednesday to choose a successor to President Lee Myung-bak, who was barred by law from seeking a second term.
