It's another laundromat, hello.
Same as most Chinese businesses, all subsidized by Chinese government and grants. Just sit and watch that junk shop in the main strip, I doubt they sell more than 10 items of 200 pesos each every day... ! It doesn't even pay for the electric let alone the rent for that place... !?
It's just a strategy for China to get their people move into other countries and basically expand their commercial empire. The next step is of course the Chinese tourists, I saw some Chinese people on the beach the other day, maybe 5 or 10, a bit of a shock as I had not noticed them before, but these are just the guys working in the shops. Once the flights coming from China and bringing hundreds of thousands (even millions) of them tourist every year you will see what happens to this place and how it changes. Over the years I have seen it with my own eyes how they move in after a while in Far East Asian countries, and I tell you, it is not pretty....! (thankfully DR is a bit far away for all this.)
