Vietnamese spend tons of money on Budapest apartments

From Daily News Hungary

While buyers from the Netherlands spent an average of 11.5 million forints (~€31,500) on real estate, Vietnamese buyers spent much more, over 60 million forints (~€164,300) 

Apart from them, the Chinese and the French also bought from the more expensive segment; the buyers of both nations spent almost 50 million forints (~€137,000) on the purchased apartment. Austrians mostly bought real estate near the western border of Hungary, for an average of 24 million forints (~€66,000). The average spending of Romanian buyers was only 13 million forints (~€36,000). This was among the lowest, as they mostly bought real estate in the eastern parts of Hungary, where real estate prices are much lower. The Dutch spent even less, and they mostly bought real estate in small towns in Southern Transdanubia.

Is it not unlogical that people from two of the remaining Communist countries spend more for apartments in Hungary than do buyers from Western economies?
