Around 1,000 protesters gathered near Hong Kong's harbor, waving pro-Uighur posters and flags - in what appears to be the latest grievance between the pro-democracy movement and China's influence. While largely peaceful, police used pepper spray to disperse the protesters. In response, protesters threw glass bottles and rocks.

"We shall not forget those who share a common goal with us, our struggle for freedom and democracy and the rage against the Chinese Communist Party," said one protester holding a megaphone.

China runs Hong Kong under a "one country, two systems" model that grants the financial capital expanded freedoms not enjoyed on the mainland. Many Hong Kongers view China as encroaching on these freedoms and fear mainland policies will come to the city.
