I just wonder, what's the difference between them?
They're so similar to me (please note that English isn't my native language and I don't study in English so the subject's name I took was translated into my native language)
I'm so curious about this since I have to choose the course and I want to choose it exactly what I want to study.
Thanks so much :)

I think the difference is that trade law is only related to commerce (like international sales of goods), while business law is broader, it includes commerce but also investment and other things...
