> I don't know Trump's real intentions.

Except his inner circle and maybe friends, I think no one knows. We can only speculate with what he says in his tirades of interviews and other public statements. China for me, seems to be the bone of contention for Trump. The Canadians and co might give in, no matter how emotionally agree that becomes, but the Chinese feels they have everything to go on a retaliatory tariff yo-yo with Trump. 
They consider themselves economically equipped, and personally I feel that Trump doesn't like this.
