A few years earlier, TPP (Trans Pacific Partnership) becomes a current topic around the world, we can hear often about it on TV or newspapers. However, there are many difficult words, and time goes without our understanding. TPP was not global like now at first, only it worked for 4 countries. Hence, it is inevitable for the people in the other countries not to know details, so I searched websites and learned the merits and demerits of TPP. I will write my opinion about TPP.
