Jeff Leung, director of the Hong Kong Economic and Trade Office in San Francisco, speaks at a news conference on June 19 about the progress and development Hong Kong has made since its handover back to China in 1997. He said Hong Kong, as an international metropolis, benefits from being part of China under the framework of "one country, two systems." This year marks the 15th anniversary of Hong Kong's return from British control. [Chang Jun / China Daily]
