What British colony became part of China again in 1997?
In 1898, the United Kingdom, concerned that Hong Kong could not be defended unless surrounding areas were also under British control, executed a 99-year lease of the New Territories, significantly expanding the size of the Hong Kong colony. The lease would expire at midnight, on June 30, 1997. Hong Kong was a crown colony of the United Kingdom from 1842 until the transfer of its sovereignty to the People’s Republic of China in 1997.
