From the article:
“Apart from the formal withdrawal of the legislation, the protesters have asked for the government to set up a commission of inquiry to investigate police conduct in tackling the protests, grant amnesty to those who have been arrested, stop characterising the protests as riots, and restart the city’s stalled political reform process.”
All that said, this is just a slogan. Different protesters put weight on different elements of this menu. Each concession takes people off the street. Given how reasonable many of the demands are, it makes sense for someone to be an adult in the room to Xi’s pettiness.
