From what I saw none of the topics brought up in the debate were about China. China was brought up when the topic was derailed by both candidates. One time Biden apparently wanted to paint Trump as a hypocrite because he said he didn't raise taxes on Americans. I don't know if Biden couldn't keep his thoughts straight but it sounded like he was bringing up Trump's tariffs on China as a tax on Americans. And Biden kept Trump's tariffs and increased them... Yeah Trump is a liar that he didn't increase American's taxes but then Biden kept and increased Trump's tariffs on China wasn't about taxing only the rich like he claimed he was doing.
