"Samsung is a major buyer of Japanese chemical companies producing fluorine polyimide used to make flexible OLED displays, as well as resist and etching gas needed in the semiconductor fabrication process."

Samsung's CEO went to Japan to try and secure Japan's chemicals back in 2019 during the bad blood between South Korea and Japan.

China will have to take on the entire supply chain from chemicals, machines and talents if they want to avoid a chokehold. That's a very tall order.
