The Canadian government on Friday blocked Petronas' proposed multibillion-dollar takeover of the Calgary company, saying it wasn't in the country's best interests.
But Progress Energy's chief executive officer, Michael Culbert, said in a statement the firm will spend the next month determining "the nature of the issues and the potential remedies," the Canadian Broadcasting Corp. reported.
"The long-term health of the natural gas industry in Canada and the development of a new [liquefied natural gas] export industry are dependent on international investments," Culbert said.
Canadian Industry Minister Christian Paradis said purchase, valued at between $5 billion and $6 billion, failed Canada's "net benefit test."
"I can confirm that I have sent a notice letter to Petronas indicating that I am not satisfied that the proposed investment is likely to be of net benefit to Canada," Paradis said a statement.
The Canadian government also is taking a look at the buyout of Nexen Inc. of Calgary by China National Offshore Oil Corp., which would be a $15.1-billion deal.
