Here is some insight to the Sunday Trump tweet.

Here is a snippet of an article in Reuters today of what prompted President Trump to dial up the tariffs again. 

The diplomatic cable from Beijing arrived in Washington late on Friday night, with systematic edits to a nearly 150-page draft trade agreement that would blow up months of negotiations between the world’s two largest economies, according to three U.S. government sources and three private sector sources briefed on the talks.

The document was riddled with reversals by China that undermined core U.S. demands; the sources told Reuters. In each of the seven chapters of the draft trade deal, China had deleted its commitments to change laws to resolve core complaints that caused the United States to launch a trade war: theft of U.S. intellectual property and trade secrets; forced technology transfers; competition policy; access to financial services; and currency manipulation.

U.S. President Donald Trump responded in a tweet on Sunday vowing to raise tariffs on $200 billion worth of Chinese goods from 10 to 25 percent on Friday – timed to land in the middle of a scheduled visit by China’s Vice Premier Liu He to Washington to continue trade talks.

There is also the issue of the US working to sell military defense equipment to Taiwan, infuriating China and its planned One China policy with that country. There are so many moving parts, and what is at stake with China. It is a multi-issue problem when viewed from afar and takes into account this is a battle over the next decade, not this season.
