Nicolae Timofti has been sworn in as Moldova's new president at a special session of parliament.
Timofti, 63, was elected on March 16 by 62-0 in the country's 101-seat legislature.
Sixty-one votes are needed to secure election and opposition Communist Party deputies boycotted the session.
The Communists also boycotted the inauguration, which was attended by the country's first two post-Soviet presidents, but not by Communist Party head Vladimir Voronin, who resigned as president in September 2009.
The Communists -- which comprise the single largest bloc in parliament but are outvoted by a coalition of three West-leaning parties -- continue not to recognize Timofti's legitimacy and have called on the public to protest his election.
Before Timofti's election, Moldova went more than 900 days without a president.
