The ministers met in Sydney for the latest round of talks among the world's leading economies, with Australia's Trade Minister Andrew Robb saying all nations were still committed to the Bali agreement struck in December.
Robb said while some G20 members raised concerns about the deal, which streamlines the global flow of goods, "every country there at the meeting did reaffirm their commitment to all nine (elements of the Bali agreement) being completed".
The Bali agreement by the World Trade Organisation's 160 members saw them commit to lowering global trade barriers, with the intention of making it easier for developing countries to trade with the developed world in global markets.
"We focused a lot on free trade being one of the leverages that we can use to boost growth in France ... investment and trade ... Are definitely the main aspects of our growth agenda," Pellerin told AFP.

The crash of Malaysia Airlines Flight MH17 on Thursday had threatened to overshadow the summit, with both Australian Prime Minister Tony Abbott and Robb meeting the Russian trade representative on the sidelines of the talks.
Russia's role in the incident has come under scrutiny amid its possible links to the separatists controlling territory in eastern Ukraine where the aircraft had come down in.
Earlier today, Robb warned that Canberra may consider trade sanctions against Moscow as a result of the crash, which killed 298 people, including 28 Australians, subject to how it "responds, cooperates and is proactive in seeking answers".
Australia, along with several other countries, already has imposed sanctions and travel bans on some Russians and Ukrainians.
