Finalizing the Trans-Pacific Partnership agreement hinges on approval from Japan and the United States, according to Japan Today. The two countries account for some 80 percent of the size of the economy to be covered by the pact, which includes 40 percent of the total global economy. Japan now believes the trade pact looks increasingly unlikely to be implemented before U.S. President Barack Obama’s tenure ends due to opposition from leading presidential candidates and some industries. The agreement could be signed as early as February if approved by all the nations. But U.S. congressional leaders appear reluctant to deal in the run-up to the presidential election as many contenders seeking party nomination are critical of the deal, including Hillary Clinton, the frontrunner in the Democratic race, and Donald Trump, favorite for the Republican ticket. Japan plans to submit bills necessary for its ratification and implementation to its Parliament during the next session that will begin in January.
