What do these mean here?
1. Does 'splintering of the pro-democracy movement' mean 'break of the movement' ?
The splintering of the pro-democracy movement in Hong Kong is a product of growing antipathy towards China. Other protest movements increasingly stress a separate identity in the territory too.
2. What does 'prize' here mean?
Hong Kongers increasingly prize their local identity. A poll last year by the Chinese University of Hong Kong found that just 9% of respondents identified themselves solely as “Chinese”, down from 32% in 1997.
3. Does 'wide of the mark' means that it is not a real issue ?
Branding demonstrators as separatists, even if wide of the mark, serves China’s political interests by discrediting moderates in the eyes of some Hong Kong residents.
