Olympic symbols' sanctity clarified

China has revised a regulation on the protection of Olympic symbols to help safeguard the legitimate interests of intellectual property rights holders - part of an effort to promote the healthy and fair development of the Games.

It was made public on Saturday after Premier Li Keqiang signed off on it.

The revision - modifying an earlier one that took effect in 2002, ahead the Beijing 2008 Olympic Games and similarly issued ahead of a coming event (in this case the Beijing 2022 Winter Olympics) - details the range, identification and protection of Olympic symbols.
