"As a matter of principle, such a trade agreement is bound to unleash some potential, is bound to create some values, bound to open up more borders, and as such historically we've always seen that as boost to economic growth," Lagarde stated.
She continued that "bringing 40 percent of global GDP together on that basis is bound to be beneficial for the global growth."
The IMF chief added that the provisions of the agreement have yet to be analyzed by the fund.
On Monday, the successful conclusion of the TPP free trade talks was announced by trade ambassadors from the participating countries of the United States, Australia, Brunei, Canada, Chile, Japan, Malaysia, Mexico, New Zealand, Peru, Singapore and Vietnam.
After years of secret negotiations, the TPP agreement is expected to introduce deregulated and streamlined trade between the member states.
There has been considerable opposition to the free trade deal from international organizations and lawmakers, who have criticized the TPP’s secrecy during negotiations, its apparent favoring of multinational corporations and its exclusion of BRICS countries.
"There are various countries that are really opening up and bearing the fiscal burden," Lagarde said. "[W]hat we are trying to help with is for those countries that are under program with the IMF to give them more fiscal space under their commitment in order to accommodate this additional burden."
Lagarde noted that such accommodation particularly relates to countries such as Jordan and Tunisia.
"We will be very open to continue discussions with these countries, because they are taking a massive burden on their books and their population, and it's a stretch for them, we know that," Lagarde stated.
The Syrian civil war has caused the highest refugee population in the world, as more than 4 million Syrians have fled to neighboring Jordan, Lebanon, Turkey, Iraq and Egypt, according to UN data.
In recent months, hundreds of thousands of Syrians fled to the European Union (EU). However, EU member states such as Germany, Austria, Slovenia and Hungary, have all but closed their borders.
