What is the relationship between tourism and affairs?

I want to ask, what is the relationship between tourism and business tourism? Tourism includes business tourism.

Business tourism refers to all travel activities carried out for business purposes. Tourism is a general term for all tourism activities, which includes exhibition tourism, incentive tourism, business tourism, festival tourism, business tourism, etc.

Tourism is the sum of all the relationships and phenomena that occur during the non-resident travel that people undertake in search of spiritual pleasure.
