Scared of going under anesthesia in Korea - is it safe?

I am really scared about having surgery under general anesthesia in Korea. While I trust Korean surgical skills, I am worried about anesthesia safety standards. Are Korean anesthesiologists properly qualified? Do reputable clinics have full-time anesthesiologists or do they bring in part-time ones? What safety equipment should a clinic have? I have heard some horror stories about clinics cutting corners on anesthesia to save costs. How can I ensure the clinic I choose takes anesthesia safety seriously? Are there any red flags I should watch out for during my consultation?
