China is celebrating the 70th anniversary of the People's Republic of China with a huge military parade in Beijing and nationwide celebrations. In Beijing, President Xi Jinping presided over a parade designed to show off the nation's military strength and its rapid rise over the past seven decades to a global power.

But in Hong Kong, where anti-government demonstrations have been raging for three months, protesters took to the streets, threatening to overshadow and disrupt Beijing's carefully crafted celebrations.
