"When we look at our FTAs, we are a beneficiary, we are not a loser," Sharma told PTI in an interview.
He said that India's share in the global trade is low and to enhance the overall economic growth, the country has to increase its share by boosting exports.
"When we are talking of the larger economic integration of Asia and going right up to the Pacific... Can India keep itself out? India cannot insulate itself. You can not grow by having a wall around ourselves. We live in a globalised world, we have to connect and integrate," he added.
"Let's not forget what is happening in the world," he said, citing examples of North American Free Trade Agreement (NAFTA); Mercosur (an alliance of Argentina, Brazil, Uruguay and Paraguay); Trans-Pacific Partnership (TPP) (involving nine countries including Australia, New Zealand and the US); and the Transatlantic Trade and Investment Partnership (TTIP).

According to media reports, the finance ministry too had raised concerns over the impact of these pacts on the Indian economy.
However, Sharma said: "When it comes to trade agreements, there is always a balance and then there is an inbuilt review mechanism. Let's not forget that India's share in global trade is still very low. It is little over 2 per cent.
"We need to double it at the earliest, because of economy of India's size cannot grow unless and until our share in global trade, including exports, increases."
