Modern and original versions of Chan and Seon

According to the answer to [this question](https://buddhism.stackexchange.com/questions/3061/modern-zen-vs-seon-chan-and-traditional-zen) there is a clear distinction between the traditional Zen practised in Japan until 19th century and its modern version invented by Suzuki. Is there such a clear distinction within Korean Seon and Chinese Chan? If not, which version of Zen do they correspond to?
