(Adds comment, detail, and updates prices) MELBOURNE, March 5 (Reuters) - London copper turned flat on Monday as upbeat comments on China's economy at the annual opening to parliament underpinned prices, while aluminum and metals used in steel dropped on concerns over proposed U.S. trade tariffs. "We think base metals, in the absence of an escalating trade war, is likely to remain range-bound in March, with a slight downside bias," said analyst Ed Meir of INTL FC Stone. "The complex should start to strengthen late in Q2, when the impact of higher seasonal demand starts to get felt."
