SEOUL (Reuters) - South Korea's new president has pledged to work out of a drab, decades-old government building in central Seoul instead of the grandiose presidential Blue House, a symbolic gesture that brings a logistical headache for his security staff.

Moon Jae-in, 64, was sworn in on Wednesday and vowed to immediately tackle the pressing problem of North Korea's advancing nuclear ambitions and to soothe tension with the United States and China.
