Re: Only solution is...
I doubt that will make a lot of difference. It was the US intelligence agencies that decided Huawei was a threat, Trump only got on board later when he found Jinping wasn't a sucker he could bully into a bad deal and decided to start a trade war.
You can argue over whether there is truth behind the US intelligence assessment or they have ulterior motives, but unlike Trump who believes them when his position of the hour agrees with them and claims they are incompetent when it doesn't, Biden goes along with them. He won't publicly single Huawei out like Trump does, but it isn't like the restrictions on them would be lifted if he's elected unless the intelligence assessment does.
The main difference it will make is that US state department negotiators will know that the marching orders they are given won't be changed without notice via presidential tweet so they can actually, you know, negotiate.
