China has warned the US that it could take "firm counter-measures" if Washington continues to show support for pro-democracy protesters in Hong Kong.
The warning came after US President Donald Trump openly supported Hong Kong protesters and signed the Human Rights and Democracy Act into law to support protesters. The act mandates to check if Hong Kong has enough autonomy. This move by US has angered China.
Mr Trump is currently seeking a deal with China, in order to end a trade war between the two countries. "The US has been disregarding facts and distorting truth," a Chinese foreign ministry statement said.
"It openly backed violent criminals who rampantly smashed facilities, set fire, assaulted innocent civilians, trampled on the rule of law, and jeopardised social order," he was quoted by BBC as saying.
Hong Kong's protests started in June against a proposed law to allow extradition to mainland China but it has since transformed into a larger pro-democracy movement.
The recently-held local council elections in Hong Kong saw a landslide victory for the pro-democracy movement, with 17 of the 18 councils now controlled by pro-democracy councillors. The elections results came as a shock to Chinese authorities. On Thursday, Chinese authorities moved into the Polytechnic University days after it had been the site of a fierce standoff between student activists and riot police. The police said they had found hundreds of petrol bombs and other home-made devices, and were dusting them for fingerprints.
