When the British handed its colony Hong Kong to Beijing in 1997, it was promised 50 years of self-government and freedoms of assembly, speech and press that are not allowed Chinese on the Communist-ruled mainland. As the city of 7.4 million people marks 25 years under Beijing's rule on Friday, those promises are wearing thin. Hong Kong's honeymoon period, when it carried on much as it always had, has passed, and its future remains uncertain, determined by forces beyond its control. (AP Photo/Kin Cheung)
