Because China wants to dominate this region and recently signed a secret military pact with the Solomon Islands, for example:

China’s influence increased significantly during the term of Manele’s predecessor, with the country switching diplomatic recognition from Taiwan to China and striking a secretive security pact that has raised fears of China’s security forces gaining a foothold in the region long dominated by the U.S., Australia and New Zealand.

Surely you must’ve read the article and understand the actual cause for concern. For example, from the article, 8 of the 10 most surveilled cities are in China:

According to an analysis by Comparitec, eight of the top 10 most surveilled cities in the world per capita are in China, where facial recognition is an inescapable part of daily life – from the facial scans required to register a new phone number, to facial recognition gates in some subway stations.

Where those cameras have been used in repressive ways:

In the far-western region of Xinjiang, Beijing has used cameras to monitor members of the Muslim-majority Uyghur population. And when unprecedented nationwide protests broke out in late 2022 against the government’s strict Covid policies, police used facial recognition along with other sophisticated surveillance tools to track down protesters, The New York Times found.

Trump and 18 others were charged in a sweeping racketeering indictment for alleged efforts to overturn the results of the 2020 presidential election in the state of Georgia. The former president says his actions were not illegal and that the investigation is politically motivated.

Hall, a Georgia bail bondsman, is charged with seven counts, including two counts of conspiracy to commit election fraud. All the defendants are also charged with violating Georgia’s Racketeer Influenced and Corrupt Organizations Act, approved by Standards/Legal, w/ photo & videoknown as RICO.

What do you mean the Canadian government tolerates it? Sterilization is illegal and prosecutable under Canadian criminal law, and the article cites the recent Senate report condemning the practice.
