The post mentions Hong Kong, which is something like this: - Hong Kong was ceded to the UK after the opium wars in 1842 - The British returned it in 1997, under an agreement that its economic and political systems wouldn't change for 50 years - starting in the 2010s (less than 20 years later), the PRC has been pressuring the Hong Kong government to drop colonial-era democratic reforms, extradite critics of China, and in general curtail civil liberties. Presumably OP is referring to the PRCs actions to integrate Hong Kong before 50 years have elapsed. I'm not an expert here, this is just my layman understanding from reading American news
