That China and Iran may prefer to see Biden as president is widely believed in the US. However, according to the FBI, there is no evidence that China, like Russia, is trying to influence elections in the US through disinformation and false profiles on social media. In July, FBI chief Wray was concerned about traditional influencing techniques such as bribery, blackmail or economic pressure with which Beijing tries to influence or silence figures from the American media, financial and economic world or in politics.
Yet many analysts think that the conflict between the US and China is so great (coronavirus, Hong Kong, Xinjiang, trade war, South China Sea, etc.) that even if Biden replaced Trump, relations would not improve immediately.
