International arbitration veteran David MacArthur is moving from Tokyo to Seoul, joining the partnership at South Korean Big Six firm Yulchon as co-leader of the disputes practice. His move comes at a time when Yulchon has been aggressively bulking up its disputes offering.

Tokyo-headquartered firm Anderson Mori & Tomotsune (AMT) has hired David MacArthur as a senior foreign counsel in the international arbitration practice and will be operating out of the firm’s Tokyo and Singapore offices from Bae Kim & Lee (BKL) where he was a partner in Seoul.
