The Cuban dissidents.
About Castro is a well-known fact, described in many sources, but few know about Den Xiaoping.
When China turned his face toward America, Bzejinsky began to threaten Deng Xiaoping, saying that the rights of dissidents were violated in China, and the United States would be forced to adopt an amendment to defend their rights, similar to the one they adopted against the USSR (Jackson-Venic amendment). To what Deng Xiaoping replied – no problem, how many Chinese dissidents are you willing to accept in the U.S. – 20 million? Thirty million?
This issue has not been raised in the negotiations.)
