KIEV, Dec. 5 – Acting Prime Minister Mykola Azarov said he regrets that the government led by him did not manage to revise gas contracts with Russia.

"We are not entirely satisfied with the fact that not all of the tasks we set ourselves were fulfilled. Much more transformations should be made. First of all, this refers to a revision of unfair terms of purchasing Russian gas," he said at a meeting of the government on Wednesday.
