“Koreans, Japanese and Chinese do not add salt to plain rice when cooking it. The raw rice needs to be agitated (swirled around using a clean hand) while running cold water over it, stopping the water then draining it -- as many times as this takes for the water in the pot to look crystal clear.
Rice comes into play because it absorbs moisture even faster than salt. You're familiar with the lifesaver of putting your water-damaged phone in a bag of uncooked rice? It's the same concept.
