May 13 (Reuters) - U.S. stocks futures extended losses on Monday after China said it planned to set import tariffs against $60 billion worth of U.S. goods.
Futures were weaker earlier after U.S. officials demanded promises of concrete changes to Chinese law and Beijing said it would not swallow any "bitter fruit" that harmed its interests.
