In ancient times, when kings visited one another, they would bring gifts as a symbol of respect and gratitude. However, what many people don't know is that the greater king always gave the greater gift. So for you to visit a king and bring a great gift was expected; if they were greater, they would send you away with what you brought plus even more as to demonstrate they were the greater king. When you give gifts, the connotation is not the same as in ancient times but you do set the standard for the culture of the relationship.
