Pro-Taiwan groups have expressed fears that their annual national day celebrations in Hong Kong next month might be deemed secessionist and banned under Basic Law Article 23. Officials responding to the worries said the government would uphold the one-China principle and act in accordance with the law. With the 'Double Tenth' due in three weeks, Taiwan-affiliated bodies have been organising low-key celebrations. Following the handover, the groups significantly scaled down their October 10 events. The date marks the revolution overthrowing the Qing dynasty in 1911 and the official celebration of the establishment of the Republic of China. Hong Kong and Kowloon Trades Union Council chairman Lee Kwok-keung said tension between Taipei and Beijing would make the celebrations this year even more low-key. He had no plans to liaise over the activities with Constitutional Affairs Secretary Stephen Lam Sui-lung, who took over the Taiwan portfolio from Paul Yip Kwok-wah, the former special adviser to Chief Executive Tung Chee-hwa in July. As before, the trade union will join others to display the Taiwan flag during a ceremony at a venue in Tuen Mun. The venue is one of the revolution strongholds of Dr Sun Yet-sen. In line with previous practice, a private celebration by the Taiwan-funded Kwang Hwa Information and Cultural Centre will be held at a hotel. It is still unclear if individual pro-Taiwan activists will fly the Taiwanese flag in public, a move which has been viewed dimly and invariably curbed by the post-handover administration. Mr Lee said Article 23, which says Hong Kong should enact its own legislation to outlaw subversion, secession and other national security-related crimes, had posed new uncertainties. 'Would we be deemed as secessionist when we display the Taiwanese flag and chant slogans like 'Long Live the Republic of China'?' he asked. 'When we fly the Taiwan flag, that means we recognise Republic of China rather than communist China. Some of us even carry Taiwanese passports,' he said. He said officials had privately assured them pro-Taiwan groups would not be targeted. Nontheless he was concerned that anti-communist criticisms in their publications might be seen as 'inciting' secession and be outlawed. In a written reply in early August, a top aide of Mr Lam said the one-China principle must be upheld regarding the display of the Taiwan flag. The bureau also stressed that groups 'uphold the one-China principle and act in accordance with the law'. Last month, Secretary for Security Regina Ip Lau Suk-yee said the community would have sufficient time to air its views after the proposals for Article 23 went out for public consultation.
