The treaty giving China these rights is like 100 years old isn't it? It's a little late to do anything about it now.
The UK gave Hong Kong back to China in 1997 or 1998.
EDIT:
The New Territories were leased from Qing China to the United Kingdom in 1898 for 99 years in the Second Convention of Peking (The Convention for the Extension of Hong Kong Territory). Upon the expiry of the lease, sovereignty was transferred to the People's Republic of China in 1997, together with the Qing-ceded territories of Hong Kong Island and Kowloon Peninsula.
So it's been a long time coming.
The sun never sets on the British Empire.
Well... not so much anymore.
