Obama and Hillary oversaw the largest US military build up in Asia since WW2 through their Asia Pivot. As a Chinese person who keeps up with these things, I can say that the Chinese government was very nervous about Obama's military aggression and so they started building bases in the south china sea etc. They aren't scared of Trump, they're just saying war is imminent because they know all the leftists in the US will jump on it to remove Trump's ability to negotiate trade deals with China (he's 100% right that China is ripping off the US, we've been doing it for like 20 years now, it's great for us).
The main problem is that Trump doesn't realize (or doesn't care) that the previous administration pointed a gun at China's head and passed it along to him, I don't know what the military industrial complex will be whispering in his ear - with Obama he just did what they told him without question because he makes money from it, with Trump I think he'll do what they want just because he's easy to manipulate and doesn't know what's going on.
We cannot accused Obama and Hilton about this, it is about the war of United States and China therefore, we must know what is their intentions. I think that President Trump cannot make a decision from now, but after a year or months later, he can decide what will happen. We cannot question him what he will do from now, I think President can manipulate or he is scared, because, it so very risky to take a decision from now.
