The Liberal Party had been the ally of the Tung Chee-hwa's administration. In March 2000, Vice-Chairwoman Selina Chow was appointed Chair of the Hong Kong Tourist Association, which was later transformed into the Hong Kong Tourism Board. The Tourist Board was regarded as the fiefdom of the Liberals. After Selina Chow stepped down in 2007, James Tien was appointed by Donald Tsang to succeed her as the chair of the board. In July 2002 when chief executive Tung Chee-hwa carried out the Principal Officials Accountability System (POAS) in the beginning of his second term. Party chairman James Tien was appointed to the Executive Council alongside the DAB chairman Tsang Yok-sing as the coalition of the Tung administration. The former Liberal Party's ExCo member Henry Tang was appointed Secretary for Commerce, Industry and Technology. However the governing coalition between Tung Chee-hwa the Beijing-loyalist DAB and the pro-business Liberal Party suffered from growing disunity as the popularity of Tung administration dropped. The Liberal Party was increasingly frustrated by unequal political exchange with the government and the skimpy political rewards meted out by Tung. James Tien even openly aired his displeasure and advocated power sharing with the government.
