Super7 in my view the English of locals can be improved with improved literacy rate as they don,t gonna learn it just to help you out and if literacy rate improves to greater extent I don,t think they would need much expats here.
So its just a matter to appoint PRO(with good english skills)at critical govt offices to interact with Expats.
Ideally police ,more importantly traffic police should also speak english,but u never know it may be a blessing in disguise lol
