In the Hall of the People in Beijing, British Prime Minister Margaret Thatcher and Chinese Premier Zhao Ziyang sign an agreement committing Britain to return Hong Kong to China in 1997 in return for terms guaranteeing a 50-year extension of its capitalist system. Hong Kong–a small peninsula and group of islands jutting out from China’s Kwangtung province–was leased by China to Great Britain in 1898 for 99 years.
