And, when China reacts, how will President Trump react to that reaction?

Where we are at, Sunday tweets from Uncle Don:

Its just going on 5 am in Beijing, we'll get a response in coming hours (give 'em a chance to have some congee first). I don't imagine they'll be too happy with this. If their response is sharp and retaliatory we could (I imagine its likely) further escalation from Trump - cancelling (might be couched as a postponement?) this week's round of talks in Washington?

This ain't over ladies and gentlemen. Stay tuned.

how will China react to Trump's tariff hike tweets?

Everyone's got a crazy uncle, right?
