Hong Kong
According to the Basic Law of Hong Kong, Chinese citizens born in Hong Kong have the right of abode in the territory; i.e. all the citizenship rights accorded to residents of Hong Kong. A 2001 court case Director of Immigration v. Chong Fung Yuen affirmed that this right extends to the children of mainland Chinese parents who themselves are not residents of Hong Kong. As a result, there has been an influx of mainland mothers giving birth in Hong Kong in order to obtain right of abode for the child. In 2009, 36% of babies born in Hong Kong were born to parents originating from Mainland China. This has resulted in backlash from some circles in Hong Kong of increase and potential stress on the territory's social welfare net and education system. Attempts to restrict benefits from such births have been struck down by the territory's courts. Segments of the Hong Kong population has reacted negatively to the phenomenon, which has exacerbated social and cultural tensions between Hong Kong and mainland China. The situation came to a boiling point in early 2012, with Hong Kongers taking to the street to protest the influx of birth tourism from mainland China.
