Manga originate from Japan, while Manwha is Korea typically. There is also a difference of Manga are normally Black and white while Manwha's are drawn with color... Additionally when reading them online Manga is normally page sized where you can see the full page on your screen, and Manwha's are in more of a webcomic design where you have to scroll down to see more of the chapter instead of clicking to the next page.
