George Friedman disagrees with you: he's been saying for years that US trade policy towards China had to change no matter who won the 2016 election (because an economy cannot rely on a trade partner it might go to war with, among other reasons).

When last year the Trump admin started interdicting oil shipments out of Venezuela, it left shipments heading to China intact. Then during Trump's visit to China, the two parties made a lot of progress on trade and other issues (in part because Beijing's attitude improved because the first Trump administration's restrictions on trade underlined to Beijing how dependent China is on trade with the US).
