HK most expensive for expats

Hong Kong has overtaken Luanda, Angola, to become the costliest city in the world for expats, according to an annual survey released by Mercer on Wednesday.

After topping Mercer's Cost of Living Report for three consecutive years, Luanda was narrowly edged by Hong Kong this year, owing to a stronger HK dollar.

The survey by Mercer, a consulting group, compares the cost of more than 200 items in more than 200 cities such as housing, food, transportation and entertainment.
