WASHINGTON (Sputnik) — The agreement needs congressional approval to go into effect, and has also received harsh criticism from other member states, including Canada and Japan.
"The idea this could be renegotiated is simply impossible," MacFarquhar said on Friday of the 6,000 page agreement reached between the United States and eleven other countries.
Last week, US Senator Orrin Hatch, who previously supported the TPP free trade agreement, called on President Barack Obama to renegotiate it.
"This is an incredibly complex agreement involving twelve countries, thousands of tariff lines, dozens of products, incredibly complex," MacFarquhar insisted, noting that the TPP agreement took seven years to finalize.
The final text of the TPP agreement was released to the public last week after it was signed in October by the United States, Brunei, Chile, New Zealand, Singapore, Australia, Canada, Japan, Malaysia, Mexico, Peru and Vietnam.
