US STOCKS-Wall St rout worsens as China hits back on trade

U.S. stock markets fell more than 2% on Monday after China announced retaliatory tariffs on U.S. goods, heightening fears of a full-blown trade war between the world's two largest economies that could cripple global economic growth. At the heart of the selloff were shares in major technology companies including Apple Inc as well as chipmakers, manufacturers and retailers that draw large chunks of their revenue from China.
