This, ROC president visiting US is big news, if it happens expect PLA reaction on the same level as Pelosi visit if not more.
But besides that, consider the implication behind this news:
1. Someone over in the states came up with the idea that "if we get Tsai to visit us instead send Americans to Taiwan it won't anger China as much"
2. People in charge listened to that idea and thought it was a good idea
3. US did this, because they wanted to avoid angering China
Well they're going to learn a thing or two from PLA then. But this news tells you the quality (or lack thereof) of decision making in US regarding China.
