China's new ethnic unity law comes into effect

Beijing's new ethnic unity law strengthens Mandarin's position as the primary language of education, official business and public spaces across China. The government says the law's provisions on social cohesion and preventing separatism benefit everyone. But minority activists abroad say it will further erode the rights of groups such as Uighurs and Tibetans. They are also warning against a clause that states China can take action against those who violate the law outside of the country. Taiwan has echoed this criticism. Its government warns the law could be used to target people there who are critical of Beijing.
