Indeed he did, that's when the vice-chair and his team were nodding and smiling in the oval office, Trump still hasn't got it... The Asian way of negotiating is to nod affirmingly at everything then continue to do as they always did, Trump keeps getting conned and market players keep falling for Trump's cons. China smiles at the idiocy in America.
As for "USDA announced Thursday export sales of 130,000 metric tons of U.S. white wheat for delivery to China, a sale that comes one week ahead of the next round of bilateral trade negotiations. It’s the first significant purchase announcement for Chinese importers above 100,000 metric tons since China slapped a 25% tariff on the grain last year.", The operative word is "expected", China later said US wheat is too costly with their 25% tariff on the grain, but they won't remove their tariff unless Trump rolls-back his tariffs, so, they agreed then made it conditional by saying they'll buy wheat from the cheapest supplier.
