China has accused the United States of working with the separatists in Hong Kong and Taiwan to undermine the country and plunge it into chaos.
In an online video posted by Chinese Supreme People's Procuratorate, the highest agency at the national level responsible for prosecution and investigation in China, apocalyptic images of Syria and Iraq are contrasted with bucolic views of today's China, reports the CNN.
"The haze of domestic and international concerns has not dispersed from the Chinese sky," says the video.
"Tibet, Xinjiang, Hong Kong and Taiwan separatism, as well as dissident leaders, lawyers who would fight until death and other agents of Western forces are damaging China's internal stability and harmony. Behind all these incidents, we can often catch a glimpse of the dark shadow of the Stars and Stripes," the video adds.
In a post on Weibo, a Chinese microblogging website, the Procuratorate also urged the people to "stay alert for color revolutions" or see "peaceful and stable China" become like Syria or Iraq.
A warning against independence movements in Taiwan and Hong Kong is overlaid on photos of Joshua Wong, a leading Hong Kong pro-democracy campaigner and Taiwanese President Tsai Ying-wen.
In a statement, Wong dismissed the video as laughable, adding that it was full of "false statements."
Beijing's warnings come as the authorities in Hong Kong barred several pro-independence politicians from standing in the upcoming elections to the Legislative Council, the city's parliament.
One of the barred politicians, Edward Leung of Hong Kong Indigenous, denounced the commission's decision as political censorship, warning that Hong Kong will never have true democracy as long as it is under Chinese control and called for a revolution.
