I'm afraid there would be no sincerity, until a more China-leaning and friendly administration is put in place in all branches of government. Even then, a majority of our population is so brainwashed, on par with Indians and MAGA, that there seems to be an irrational baseless hate towards the Chinese. The SCS dispute is insufficient to explain it, it's as if our entire history was under oppressive Chinese colonial rule for hundreds of years...or we just have the loudest and most annoying online troll presence per gdp capita in the world.
