News of trade spat between U.S., China over paper import tariffs to U.S. unlikely to affect short-term base metals trade much though if protectionist measures spread, could impact physical market; "this is all speculation right now and we don't know anything firm," trader says. 3-month copper at $6,875/ton, +$25 on Friday PM kerb but off intraday high of $6,910.
