China is running into one of the problems of Communism; once the government controls a company, what that company buys is fair game in treaty negotiations. China's government owns a lot of Chinese companies. The world already knows this, but Trump is the first president to figure it out.
Neither Trump nor Xi are attempting any kind of long term trade deal. Xi will only accept a deal where China can grow enough to eradicate the English language from Western culture and the Magna Carta is forgotten, in which case a trade deal wouldn't be necessary anyway. Trump will only accept a trade deal in which that can't happen.
No deal is anticipated by either. Both are vying for time and ways to milk money away from the other to fund their own goals, which are already known, though not everyone has figured them out because not many people want to. We're on a collision course with war and no one wants to admit that.
Delaying the October 1 tariffs because 1. the Chinese premier asked for it and 2. because of the 70th Anniversary celebrating the Chinese Communist Party will only embolden the Chinese Communists. The Chinese love parades, and if they think America respects their parades, they will think it proves that they are invincible. This is a part of Chinese thinking Americans struggle to understand.
Equally, the Chinese struggle to understand Trump. In his Tweet announcement, where he delays the tariffs, but also reminds everyone how bad they will be just two weeks later—it's a mind game that Beijing can't grasp. Even reading this article won't help the Chinese get wise to how much they are being played. The only reason they are so easy to play is because they make it so easy by refusing to abandon their Confucian values. Ironically, those are the very values they want to impose on the rest of the world by Sinicizing the rest of the world.
So, mid-October has become the big date. That's when Trump slaps more tariffs on China, and that's when Taiwan is expected to finalize its purchase of 66 brand-new, shiny, American F-16Vs.
