*explains*
Hong Kong is a SAR of China; the city was under British rule less than 100 years ago.
Deng Xiaoping (did i spell his name correctly?) made an agreement with the British governor that all of Hong Kong(all the islands, everything) will be returned to China on July 7th, 1997.
It had something to do with the 99-year rent. Or something like that.
That's all I know. Blame my lack of knowledge.
