From the South China Morning Post this week in 1984
With a stroke of a pen, British Prime Minister Margaret Thatcher officially endorsed the return of Hong Kong to China - to take effect after 155 years of British rule over the territory.
The agreement would take immediate effect within six months and a joint liaison group would be formed to oversee the transfer of sovereignty on July 1, 1997.
Both Chinese and British leaders hailed the signing as a fresh example of nations solving problems left over from history through peaceful negotiations.
Nearly all influential members of the Chinese Politburo attended the signing ceremony in the Great Hall of the People.
They included China's top leader, Deng Xiaoping , prime minister Zhao Ziyang and president Li Xiannian.
