Not only does the USA accuse China of stealing intellectual property, but it wants Beijing to make changes to its economic policies, which it says unfairly favour domestic companies through subsidies.
Nicole Kaeding, vice-president of federal and special projects at the Washington-based Tax Foundation, said that if the Trump administration follows through on the president's threat, it's United States taxpayers, not Chinese taxpayers, who will pay the price - thanks to higher prices and fewer job opportunities.
The stripping of binding legal language from the draft struck directly at the highest priority of US Trade Representative Robert Lighthizer - who views changes to Chinese laws as essential to verifying compliance after years of what US officials have called empty reform promises.
Trump also threatened on Sunday to levy tariffs on an additional US$325 billion of China's goods, on top of the US$250 billion of its products already hit by import taxes. "But for now. come Friday there will be tariffs in place", he said. He added that he was "very happy with over $100 billion a year in Tariffs filling US coffers".
USA government and private sector sources previously told Reuters that a draft trade agreement was riddled with reversals by China that undermined core U.S. demands.

Boeing Co, the single largest USA exporter to China slipped 0.5%, while chipmakers, which get a large chunk of their revenue from China, also declined.
China could make some concessions to prolong talks even after tariffs and retaliation.
Shares of chipmakers, which get a large portion of the revenue from China, continued to slide, with the Philadelphia semiconductor index ending 1.2 per cent lower.
The Dow Jones Industrial Average slid 66.47 points or 0.3 percent, after being down nearly 500 points earlier in the session. Gordan Chang, author of "The Coming Collapse of China", told Yahoo Finance Tuesday that in this case, "China has more to lose". While nearly no cars are imported from China (GM imports a small number of smaller SUVs that it makes in China), a good number of vehicle parts are, which will increase the cost of making trucks and SUVs in the United States.
The stock price of Korea's No. 2 chipmaker, SK hynix, dropped 5.35 percent from the previous session to 76,000 won ($64.35). Exports to China jumped 23.6% in March. That uncertainty has weighed on investor confidence around the world, and has contributed to losses.
