The Chinese are smart and they know how to play the game. They run circles around the local business owners no matter who the host country may be.
They had a major dust up further down the road around Av.Duarte y 27 de Feb about 10 years ago because the Chinese run shops were only hiring Haitians. A lot of cussin and fussin ensued and afterwards they started hiring more Dominicans but it was short lived.
The Chinese tend to favor the Haitians over the Dominicans, according to what I was told by a Chinese business owner down in the Capital, because they work harder and steal less.
All of these Chinese business owners are members of their local Chinese Business Association/ "Guanxi" networks. These same associations have no problem with "lobbying"/ playing politics to make things run as smooth as possible for their fellow countrymen and I hate to say it but this probably includes immigration related issues as well.
Talk about a rabbit hole...
One could easy write a book about this topic.
They all take credit cards and offer comprobante fiscals though, I think the DGII won that battle. But employment-wise, they are definitely winning right now.
