Richard Norland will lead the diplomatic effort to reach a political settlement in the country.
The United States has appointed its ambassador to Libya, Richard Norland, as its special representative for the country, the State Department said.
He will lead diplomatic efforts to reach a negotiated political settlement in the country, the statement said.
The appointment was preceded by the election of the Presidential Council, which currently serves as the Head of State, in a process facilitated by the United Nations.
A national unity government was also formed, which took office in March, replacing rival administrations in the east and west.
