"So far, we are still at the stage of negotiations, but we have a very large capacity and need substantial volumes," Jean-Francois Cirelli said.
He said the company needs 100 billion cubic meters of natural gas, Russian gas currently meeting 15% of demand.
He said the company was looking to expand its presence in Russia both in hydrocarbons production and in power generation.
"In the future, we would like to make large investments in Russia," he said.
The executive said the company had reached an agreement with Gazprom to set up a joint venture that would implement energy-saving and energy-efficiency projects.
Cirelli did not offer a timeline, but said "we will teach Gazprom how to save gas."
GDF Suez, which has terminals in North and South America, Asia and Europe, earlier said it was capable of providing Gazprom more security and flexibility in LNG sales.
