The US already crosses 3 of these (democracy & human rights, China's system, development without infringement), 2 of them (democracy and human rights, development without infringement) very flagrantly with their constant attacks and sanctions around Xinjiang and in general against China and their restrictions on high technology such as chips including China selling gear such as Huawei products. And of course they're constantly trying to overthrow and change China's system with color revolutions, sponsoring terrorism and separatism, fostering liberalism, pushing propaganda, but it's a lower key thing.

They will cross the fourth red line (Taiwan) within 3-4 years I can be nearly certain.

US: "Red lines? Hold my beer"

Draw the four red lines in a square around the country and tell them to stay the fuck inside

I hope Biden's handlers were listening closely.

• Taiwan
• Democracy and human rights
• China's path and system
• China's development right
