The 31-times Bulgarian champions will become the first foreign team to play in the African country after the uprising against Muammar Gaddafi's rule erupted on February 17 last year.
"We are very grateful to the Bulgarian team, who agreed to participate in this historic event for Libya," the embassy told Reuters by email on Sunday.
The Libyan league has been suspended since last February but clubs have continued to play in continental competitions, by forfeiting their right to play at home in knockout ties, which were reduced to a single match at their opponent's ground.
The matches will take place at the "Benina Martyrs" stadium in the eastern town of Benghazi, which is about 1,000 kms east of the capital Tripoli with capacity crowds expected for all games.
Asked why a Bulgarian side had been invited, he replied: "This tournament is organised by a political party and they have business relations with the CSKA president so they offered to play this tournament and he accepted."
