First of all a BIG CONGRATULATIONS to @dubem-eu & @daystarseu for great contribution to last week debate, Weldon guys <3

To me there are two intentions behind large trade agreements among two different nations. Actually the countries have to follow the so called international laws to minimize the hatred to exchange different things with each other on macro level. This thing also build a good relationship among the trading countries, yes trading agreements benefits the governments as a whole.

Lets have another look upon this; trading ideas and benefits also help one country to achieve it's violent approach against any country.
For example if the superpower of the world wants to attack any third world country but can't approach directly to that country then, having a greedy trade agreement with neighboring country of the target country would help the superpower of the world to achieve it's aim. So, overall it is helpful to countries.

P.S: In many aspects governments are controlled by the large corporations all over the world, so indirectly trading ideas help these corporations.
