The U.S.' threat of an additional 200-billion-dollars worth of tariffs on Chinese goods caused a sell-off in Chinese markets and knocked Asian stocks. 

According to senior U.S. administration officials Tuesday, Washington proposed the additional tariffs after negotiations aimed at finding a solution to the trade dispute failed to materialize an agreement.
