If South Korea wants to get tough on leaks to China, it needs to stop building factories in a country notorious for its industrial espionage programs. The South's relentless poaching of technology and talent will only escalate if it continues to expand manufacturing in the Chinese market. Seoul is at risk of losing its technological advantage to the PRC if it does not join the West in tightening its semiconductor trade.
Instead of pointing the finger at China, South Korea would be wise to take a hard look at America's punitive export controls that have forced Chinese firms to target South Korean talent. If America lessened its aggressive and ill-advised export control policy, competition would be much less cutthroat. Seoul cannot afford to begin antagonizing its most important trading partner.
