Hi, I want to know how important a meeting is between 2 leaders. I know that it is very important, but I want to know in detail. Thank you in advance.

It provides an exchange of ideas in order to solve a problem. IF there is no exchange, one would have to be a dictator? It's why discussions, debates, etc. are a valuable tool. Have you heard the expression, "two heads are better than one?"
