The minister said Thursday the collective labor contract at CFR Marfa is valid until April 2014.
CFR Marfa employs some 9,000 people.
GFR will pay EUR202 million for a 51% stake in state-run freight rail carrier CFR Marfa, Fenechiu said earlier Thursday.
Its offer was EUR22 million higher than the EUR180 million asking price.
The privatization of CFR Marfa is prerequisite for the successful completion of a EUR3.6 billion loan program Romania and the International Monetary Fund have signed two years ago.
GFR has undertaken additional investments of 900 million lei (EUR202 million) in CFR Marfa, Fenechiu said.
He added the sale agreement will likely be concluded next week. (EUR1=RON4.4534)
