Sup-Joon Byun

"Regarding my interest in VIAC, I have recently worked on arbitration matters with Austrian clients and Austrian co-counsel involving Korean companies, and I believe that Vienna has the potential to replace Singapore and Hong Kong as the preferred neutral arbitration destination for Korean users. I look forward to contributing as much as I can to further grow VIAC’s position in Korea and Asia."
