In 1983, when the United Kingdom reclassified Hong Kong from a British crown colony to a dependent territory, the governments of the United Kingdom and China were already discussing the issue of Hong Kong's sovereignty due to the impending expiry (within two decades) of the lease of the New Territories. In 1984, the Sino-British Joint Declaration – an agreement to transfer sovereignty to the People's Republic of China in 1997 – was signed. It stipulated that Hong Kong would be governed as a special administrative region, retaining its laws and a high degree of autonomy for at least 50 years after the transfer. The Hong Kong Basic Law, which would serve as the constitutional document after the transfer, was ratified in 1990.
• Since 1997
On 1 July 1997, the transfer of sovereignty from United Kingdom to the PRC occurred, officially ending 156 years of British colonial rule. Hong Kong became China's first special administrative region, and Tung Chee Hwa took office as the first Chief Executive of Hong Kong. That same year, Hong Kong suffered an economic double blow from the Asian financial crisis and the H5N1 avian influenza. In 2003, Hong Kong was gravely affected by the outbreak of severe acute respiratory syndrome (SARS). The World Health Organization reported 1,755 infected and 299 deaths in Hong Kong. An estimated 380 million Hong Kong dollars (US$48.9 million) in contracts were lost as a result of the epidemic.
On 10 March 2005, Tung Chee Hwa announced his resignation as Chief Executive due to "health problems". Donald Tsang, the Chief Secretary for Administration at the time, entered the 2005 election unopposed and became the second Chief Executive of Hong Kong on 21 June 2005. In 2007, Tsang won the Chief Executive election and continued his second term in office.
