HK's Joshua Wong: 'Street activism is not enough'

Hong Kong activist Joshua Wong was the young face of the Umbrella Movement in 2014 which saw widespread pro-democracy street protests.

Two years on, he is launching the city's newest political party, Demosisto, with the hopes of setting a new political agenda.

Joshua Wong met the BBC's Juliana Liu to explain his party's goals and how it differs from other pro-democracy groups.
