Raul, 76, officially replaced his brother Fidel Castro, 81, who had handed power provisionally to Raul on July 31, 2006 due to a severe intestinal illness, from which he is still recovering.
Sunday's session began with the swearing of 597 deputies, out of a total of 614 elected in January.
The session began at 10 A.M. local time (1500 GMT) under the aegis of Maria Ester Reus, head of the National Electoral Commission who is also the nation's justice minister.
During this session, the Cuban National Assembly of People's Power also chose the nation's Council of State, a 31-strong body which will govern Cuba for five years. This council in turn elected a president, who is also the leader of the nation.
The council is made up of a president, a vice president, five junior vice presidents and 23 members.
