Choi Sang-mok, South Korea's minister of economy and finance, is set to begin his scheduled duties as acting president on Friday, Yonhap news agency reported, citing his office.

Choi, also the deputy prime minister for economic affairs, is poised to assume the role following the suspension of acting President Han Duck-soo's duties after the opposition-controlled National Assembly passed a motion to impeach Han earlier Friday, the report said.
