I looked it up — China still has 15 medals and the USA 9, so nothing has changed. But I think on the final day we have more swimming finals and also diving finals, so there’s still a chance.
It's very very unlikely that USA will reach China in the medal table. Only 9 events are remaining and United States will compete in 8 of them.
I think there are even just 5 events left, except I'm looking the wrong data page.

What an awful round for me...
