MELBOURNE, Sept 24 (Reuters) – London copper eased on Monday as buying was thinned by holidays in China and Japan and fresh jitters on global trade, a session after it notched up its biggest one-day advance in more than five years. Trade war worries had eased last week on expectations that any impact to global growth from an escalating trade war between the world’s top two economies would not be as big as feared. However, China cancelled an upcoming trade talks with the U.S. at the weekend, underlining the fragility of negotiations. “The news that the Chinese will not send a delegation to Washington for the proposed trade talks has duly sent the markets heading back down again,” said broker Kingdom Futures in a report. “The falls currently seen in the metals are not that big so far and the European opening will be key as much of Friday’s rally appeared to be short covering and any dips from those levels may be seen as a buying opportunity.”FUNDAMENTALS:
