SINGAPORE, Dec 17 (Reuters) - London copper prices dipped on Tuesday as investors waited for more clarity on the interim Sino-U.S. trade deal announced last week amid differing views from both sides.
The deal will be signed in early January, U.S. trade negotiators say. But important differences between what U.S. and Chinese officials say has been agreed upon have arisen in recent days, including about timing.
Top White House adviser Larry Kudlow on Monday said the deal had been "absolutely completed" and U.S. exports to China would double under the agreement.
However, Chinese officials have been more wary in their wordings about the content of the deal and did not confirm the January timing.
Three-month copper on the London Metal Exchange (LME) fell 0.3% to $6,182.50 a tonne by 0223 GMT, after a 1.1% gain in the previous session. It hit a seven-month high on Friday, when U.S. Trade Representative Robert Lighthizer announced the deal.
The most-traded copper contract on the Shanghai Futures Exchange (ShFE) rose 0.4% to 49,160 yuan ($6,984.05) a tonne, reflecting gains in London overnight.
