HANOI, Feb 20 (Reuters) - Vietnam's state oil firm PetroVietnam said on Tuesday it is not satisfied with a court decision that favoured Russian power equipment manufacturer Power Machines in a legal case against PetroVietnam.

"The content of the judgment contained serious errors, affecting the outcome of the lawsuit and depriving PetroVietnam of fair rights," PetroVietnam said. (Reporting by Khanh Vu; Editing by Kanupriya Kapoor)
