Also at the Diplomat, a bit about the efforts of some South Korean firms to disentangle themselves from the Chinese market:
The SCMP report describing the decision-making of firms such as Lotte and Samsung gave several reasons for this, including the threat of political uncertainty in China, concerns over industrial espionage, and the need to diversify in face of the threat of U.S. sanctions. Chinese protests of the U.S. THAAD deployment in South Korea, for example, left South Korean companies unsettled about the security of their investments. Similarly, the unstable regulatory landscape in China, where provincial and central governments have different priorities and strategies, often left South Korean companies at a loss regarding nationwide strategy. Finally, South Korean firms have, due to a variety of factors, found their competitive advantages over local firms eroded in the Chinese market.
