Obviously striking the TPP deal is a political process in itself. But politics and economics are dialectically interlinked domains/processes. Although TPP could be seen as a politically motivated project, it will also set an additional non-negligible conduit for economic considerations to be transpired into international as well as local politics. Thus, being a rule-based framework for cooperation among economically important players, TPP will most probably constitute a considerable impulse for the regional economies and, indirectly, to global economy.
Of course the future success or failure of TPP, as well as the risks to potential losers from this deal, will depend again on future interplay between international politics and economics, but as an undertaking, I think, TPP deal is unequivocally positive news for the world economy.
