Chief Executive Leung Chun-ying said today the government and society had a duty to educate young people on Hong Kong’s relationship with the mainland as the convenor of a new pro-independence party compared his organisation to a secretive revolutionary group. Leung’s comments also came after the launch of Demosisto, another new political party, formed by a group of student activists including former Scholarism convenor Joshua Wong Chi-fung. Wong pledged to hold a referendum in 10 years to decide the future of Hong Kong after 2047 when the principle of “one country, two systems” was to expire. The group said independence would be listed as an option in the plebiscite. They’re young, vocal and very, very determined ... but how do Hong Kong’s newest political parties differ? Responding to reporters’ questions before the Executive Council meeting on Tuesday, Leung said the issues of sovereignty and keeping the territory whole were serious, and therefore needed to be clearly explained to young people in the city. Leung stated that under the Basic Law Hong Kong was an inalienable part of the mainland. “This fact and provision do not have any time limit,” he said. The chief executive also emphasised that the Sino-British Joint Declaration did not say Hong Kong’s sovereignty could change after 50 years. In response to some young people’s dissatisfaction that democracy had not been fully implemented since the handover in 1997, Leung said under “one country, two systems”, Hong Kong enjoyed a much greater degree of autonomy compared to cities on the mainland. Meanwhile, pro-independence Hong Kong National Party’s convenor Chan Ho-tin likened his aims to those of a revolutionary group that needed to keep itself secretive. Speaking on a Commercial Radio programme on Tuesday, Chan said secrecy was necessary to allow his fellow party members to fan out across the city’s various sectors and do their work. Hong Kong independence not feasible ... for now, says new pro-democracy group Demosisto “We closely resemble a revolutionary party,” said Chan. “There is no reason for us to publicise our identities.” Chan said the idea of founding the party came in the wake of the city’s Occupy Central movement in 2014, when he said he realised Hongkongers needed to ask the Communist Party to obtain democracy but that the party would never concede. “So the only way out is to separate ourselves from China,” he said. He believed the central government was unlikely to crack down militarily on Hong Kong because of the city’s financial status and role in helping mainland officials transfer their wealth. The recent Panama Papers leak showing Hong Kong to be the largest centre for financial intermediaries helping clients transfer money offshore offered proof, he said. Chan added the Hong Kong independence movement only emerged in recent years, after Leung took office in 2012, because Beijing, through Leung, had exerted more influence on local matters than in the past. He reiterated an earlier statement that his party had no qualms achieving its goals through violence.
