hong kong handover

On Friday, President Xi Jinping will leave mainland China for the first time in more than two years to mark the 25th anniversary of the UK's handover of Hong Kong to the People's Republic. It's the halfway mark for the "one country, two systems" deal with the Brits for the territory to enjoy (limited) democracy for 50 years. We asked Eurasia Group analyst Neil Thomas to shed some light on why this date is such a big deal for Xi and the future of Hong Kong.
