The changing face of New York's Chinatown
5 February 2014 Last updated at 16:29 GMT
While Chinatowns are a feature of many US cities, some of the best known are succumbing to gentrification, campaigners say.
Manhattan's Chinatown, however, has remained a thriving immigrant community - though some are now concerned that this may be changing as more outsiders move into the neighbourhood.
"Chinatowns are turning into a sanitised ethnic playground for the rich to satisfy their exotic appetite for a dim sum and fortune cookie fix," says Andrew Leong, one of the authors of a recent report that charted gentrification in New York, Boston and Philadelphia.
The BBC went to New York's Chinatown during the community's new year celebrations to find out how the community is being transformed.
