On paper, it aims to promote integration among the 56 officially recognised ethnic groups, dominated by the Han Chinese, through education and housing. But critics say it cuts people off from their language and culture. It mandates that all children should be taught Mandarin before kindergarten and up until the end of high school. Previously students could study most of the curriculum in their native language such as Tibetan, Uyghur or Mongolian. The law was approved on Thursday as the annual rubber-stamp parliamentary session drew to an end.

"The law is consistent with a dramatic recent policy shift, to suppress the ethnic diversity formally recognised since 1949," Magnus Fiskesjö, an associate professor of anthropology at Cornell University said in a university report. "The children of the next generation are now isolated and brutally forced to forget their own language and culture." However, Beijing argues that teaching the next generation Mandarin will help their job prospects. t also says the law for "Promoting Ethnic Unity and Progress" is crucial for promoting "modernisation through greater unity". The law was voted and passed on Thursday at the National People's Congress in Beijing, which has never rejected an item on its agenda. The law also provides a legal basis to prosecute parents or guardians who may instil what it described as "detrimental" views in children which would affect ethnic harmony and it calls for "mutually embedded community environments" which some analysts believe could result in the break up of minority-heavy neighbourhoods. The Chinese government started to push for what it describes as the "sinicisation" of minority groups in the late 2000s and create a more unified national identity by assimilating ethnic groups into the dominant Han culture. Han Chinese make up more than 90% of the country's 1.4 billion people. (BBC)
