Japan will join 11 nations already in talks on the TPP: the United States, Canada, Mexico, Peru, Chile, Vietnam, Malaysia, Singapore, Brunei, Australia and New Zealand. Members hope to reach a deal by the end of this year. 

With the world's third-largest economy on board, the final TPP pact would cover nearly 40 percent of global economic output and one-third of all world trade.
