Tens of thousands of people have been blocking parts of the city for days. They are demanding that China withdraw plans to vet candidates for the next leadership election in 2017. Current leader CY Leung has urged the protesters to go home, and Chinese President Xi Jinping has reaffirmed Beijing's influence on the territory.
On Tuesday Mr Xi told Communist Party leaders in Beijing that his government would "unswervingly implement the guidelines of 'one country, two systems' and the Basic Law, and steadfastly safeguard the long-term prosperity and stability of Hong Kong and Macau".
Beijing ruled last month that Hong Kong people could elect their next leader in 2017, but the choice of candidates would be restricted to two or three people who must be approved by the majority of a pro-Beijing committee - meaning the Chinese government can effectively screen candidates.
The protests are seen as a direct challenge to Beijing's grip on the territory's politics.
Analysts say Communist Party leaders are worried that calls for democracy could spread to cities on the mainland.
They may shut down twitter, but there are other ways to get the word out. Beijing needs to tread carefully, because Hong Kong is unique to China and they could end up destroying it if they keep pushing for politcal control instead of the voters choice. It can only lead to disaster if China wins this battle, the two system way will disappear and Hong Kong as we know it will disappear. If Beijing wants peace they need to back off their demands, if they win the battle I could see a lot of international companies moving out and the economy of Hong Kong taking a nose dive. Exactly what China doesn't want, but will get if they keep pushing the buttons.
One can only hope China keeps a cool head and doesn't turn up the heat on the protestors who are not only peaceful, they are cleaning up after themselves. If China decides to become violent, it could backfire not only with protestors but also the international community and companies. They have to worry about the safety of their employees if China throws the military into the mix.
Did Britain really think China would honor the entire aggreement? Foolish if they did, as China couldn't wait any longer to throw it's political force into Hong Kong. God help Hong Kong if they survive this, only to face it again by 2047. If they do the Hong Kong people love will definitely disappear for good.Hong Kong democracy timeline
