According to the Flora of China, Cornus chinensis is restricted to China (but perhaps also found in Burma (Myanmar)). Wikipedia has an excellent account of the morphological diversity in the dogwoods, in case you were wondering why this particular species doesn't look like many of the more familiar ornamental species and cultivars.

Does resemble commonly planted Cornus mas.
My first thought was the same as Ron B. looks like Cornus mas, the fruit is edible on this one as well.

Just to clarify, I already knew the species and was pointing out that it resembles C. mas.
