I believe that no martial art is 'pure'. The Korean styles have influence from Japan and China. The Chinese styles have influences from Japan, Korea, other Chinese styles, and India.
One exception might be the fighting styles of isolated peoples in the third world. But if they have had trade, communication, war, or any other influence from other places they share ideas.
Arguably the oldest style is Greek Pancreation and was spread during Alexander the Greats Crusade.
The reality is that most of this history is lost and what remains is subjective to the views of the historians.
I love Korean styles and I don't mind a bit that they are built on the shoulders of giants like the Japanese martial arts and Chinese martial arts. The cross pollination of ideas is what makes them great!
