Biden is playing classic "Good cop-Bad cop" routine with Pelosi-visit to Taiwan.
- On one hand, Biden is going to lift massive amounts of China Tariffs to fight inflation, opening himself to criticism of "weak on China" by opponents.
- On another hand, Biden is defacto sending Pelosi, so he can claim to be "tough on China".
- While on another hand, Biden is publicly saying the visit "not a good idea" because he has a phone call with Xi Jinping in less than 1 week to discuss relations.
So on the whole, Biden can do both (Lift Tariffs, Appear Tough via Pelosi-visit) to appear like he is "Tough Man", but in reality, he is doing "Good cop-Bad cop" routine via Pelosi-proxy for domestic audience purposes.
