Vito tells Sollozzo that he is meeting with him because he is a good business man and a man to be treated with respect. Who told Vito this? Tom? Tattaglia?
I think it was Vito trying to be diplomatic, and to soften the blow he was about to deliver to Sollozzo, and through him, to
Tattaglia. As we know, he had no respect for Tattaglia because Tat was a pimp.
