As the United States and China finally seemed close to reaching a trade deal months in the making, President Trump threatened a new round of tariffs on Beijing. In a pair of Sunday tweets, he gave a Friday deadline for a deal and threatened a penalty of 25% tariffs on Chinese imports if Beijing failed to comply. Normally such a threat from a U.S. president as they try to finalize a complex trade deal would be defining moment, but on Monday most everyone seemed to have shrugged it off by mid-afternoon.

The reason? Trump’s Twitter threats have lost their shine.
