The Center for Strategic and International Studies said if Obama can work with Republicans and address divisions within his own Democratic party over the Trans-Pacific Partnership, or TPP, legislation to facilitate the pact could be passed midyear, enabling TPP's conclusion this fall.
Since the November elections that saw Democrats lose control of the Senate, Republican party leaders have identified trade as a potential area of cooperation with Obama, but divisive politics and strong opposition to TPP among many Democrats and labor unions still stand in the way of a deal.
In a year-ahead look at US policy toward Asia, the think tank said in a report that more leadership from Obama to win over Congress would resonate among the other 11 governments negotiating TPP, especially Japan, which is reticent on opening up its farming and auto sectors.
It also urged Japan, where the government just won a new term, to reach agreement on TPP.
Delays in finalizing the pact and instability in the Middle East have raised doubts over whether Obama can follow through on his attempt to shift more attention toward Washington's engagement in the Asia-Pacific.
