In East Asia, China-South Korea relations have turned rocky over the past ten years, due to frustration on the part of China over South Korea's continued military alliance with the U.S. (e.g. the THAAD radar issue in 2017 that ended by ruining the burgeoning Korean Lotte network of shopping centers across China). Samsung used to be huge in China, but now it's largely domestic brands Huawei, Xiaomi, Oppo et al. Samsung had a massive phone assembly plant in Tianjin, but moved to northern Vietnam.

From a Korea perspective, the proprietorial attitude of many Chinese ("Korea used be part of China" Xi Jinping told Donald Trump), and the penumbra of nationalism in the PRC have resulted in a major shift in public opinion from 2000. Now some 80% of South Korean youth view China unfavorably, and that seems unlikely to improve in the near future.
