I was in Taiwan for a week in feb and they were very aggressive about mitigation. Questionnaire, interview and temp checks for all airport arrivals. Mandatory temp checkpoints and hand sanitizer at basically every tourist destination, hotel, large business, temple, or public gathering place. basically everyone wearing masks (voluntarily). An army of workers on the streets continuously cleaning and sanitizing public use things (handrails, elevator buttons, doorknobs, water fountains, vending machine buttons). I don't think i rode and escalator that didnt have a PPE'd up old lady at the top scrubbing the handrail with sanitizer. Also basically no travel from mainland china from day 1.
