BEIJING, March 27 (Reuters) - Most base metals prices climbed on Tuesday, lifted by a rebound in equities on hopes that a trade war between top metals consumer China and the United States may be avoided. Senior U.S. officials are asking China to cut tariffs on imported cars, allow foreign majority ownership of financial services firms and buy more U.S.-made semiconductors in negotiations to avoid plans to slap tariffs on a host of Chinese goods.
