National Security Adviser Robert O’Brien said on Sunday that the United States is “examining other options” after more than 50 activists were arrested in Hong Kong.

O’Brien described some 55 arrests last week, the largest mass arrests since China passed a new national security law in Hong Kong, as “politicized” and “the latest of many successive pins that Beijing has pushed into the coffin of Hong Kong’s democracy.”

“The United States was the first major country with the courage and conviction to openly acknowledge the true nature of the Chinese Communist Party regime,” O’Brien said in a statement. “It is very important that countries in the world demand accountability from Beijing.”

“The world cannot continue to pay exorbitant prices for its gullibility and complicity in Beijing’s irresponsible and harmful practices – whether it is ending the rule of law in Hong Kong or not cooperating with health officials on the epidemic,” he continued. “The United States is considering more options to respond.”

China supported the National Security Act last year, which was designed to criminalize foreign interference, sabotage, and secession. Western governments and Hong Kong activists have criticized the law, saying it threatens the “one country, two systems” rule that China agreed to upon taking control of Hong Kong in 1997.

Hong Kong officials criticized the joint message from foreign officials, saying, “I was horrified by the remarks made by some government officials abroad that seem to indicate that people with certain political beliefs should be immune to legal sanctions.”

The National Security Act was passed more than a year after Hong Kong’s pro-democracy protests rocked the city over a now-withdrawn bill that would have allowed the extradition of suspects to China.
