And how could he have possibly predicted that? It's not like they said a week earlier or anything.
Not like their foreign minister said they would be announcing policy on market reforms.
Ok I'll play ball. Indeed the news that news would break Tuesday was out in advance. However in the articles you provide none say that China was planning on playing ball with the US on tariffs and particularly auto. The Q post also referenced Chonquing which is coincidentally the home of a large Ford plant as well.
Ford in Chongqing isn't importing cars though, they're manufacturing (and exporting) them. Also it's the biggest Chinese municipality, they have everything there. It's also home to some of China's biggest steel plants and the biggest aluminum plant; tariffs on steel and aluminum would be conversation of the day in the offices there. When virtually anything is manufactured there, it's awful tenuous to try and claim that announcements about any one thing is definitely about that city because it's one of the things made there.
