Yes, they did, the played by their own rules.Has they ever play by the rules?
I am sure Biden can produce many examples of xi Jin ping being a thug
1) forcefully claiming scs islands even when icj has ruled against them (xi commands the military)
2) threats against Taiwan
3) going against 1 country 2 system in hk
4) family members hiding over 1b++ of wealth under assumed names and layers of companies overseas
5) dictatorship and jailing/beating up of citizens and political opponents
Biden surely can produce at least a stack of examples
