Where is the largest population in Vientiane, Laos, China? Is there a Chinatown?

"Chinatown" seems to have no official name. There are two China markets in Vientiane: an old one (called "Dalajing" or "Dalalian" in Lao, that is, afternoon market) and a new one (called "Dalajiang" in Lao, that is, Sanjiang market), both of which are located in the urban areas, not far away, where China people are concentrated. In addition, shops opened by China people are scattered all over the city, selling hardware.
