Portraits of persistence: the Hongkongers refusing to let June 4 fade Other leaders of the movement, including Xiang Xiaoji, Wang Juntao, Wu’er Kaixi and Su Xiaokang would also join the organisation, along with US democracy expert Larry Diamond, veteran sinologist Perry Link and Lin Fei-fan, the leader of Taiwan’s Sunflower Student Movement, according to Wong on Saturday. “Facing the increasing suppression from the Chinese regime, we always believe a better connection with civil society and the international community would be important to push for Hong Kong’s democracy,” Wong, co-founder of the city’s youngest political party, Demosisto, said. Demosisto to shift focus from Legco seats to social movements Beijing had repeatedly warned of the links between forces calling for independence in Hong Kong and Taiwan. When asked if he expected a new round of criticism by joining the think tank, Wong said: “Beijing has already been suppressing us. We are not worried at all.” Beijing has already been suppressing us. We are not worried at all Joshua Wong However, as Wong is on bail pending an appeal and faces travel restrictions, Jeffrey Ngo, a standing committee member of Demosisto, would speak for him at Monday’s seminar, titled “China’s Threat to Global Freedom and Democracy”. The think tank would be launched at the event. In January, Wong was jailed for contempt of court during the 2014 Occupy protests , a civil disobedience movement for greater democracy. Meanwhile, about 30 people marched to Beijing’s liaison office in the city on Saturday to call for the release of mainland activists jailed over their mourning for victims of the June 4 crackdown. They urged an end to “one-party rule” and vindication for the protesters. Lee Cheuk-yan, secretary of the Hong Kong Alliance in Support of Patriotic Democratic Movements of China, the organiser of the rally and the annual candlelight vigil in Hong Kong to commemorate the Tiananmen crackdown, called for more people to join the demonstration on Monday.
