SINGAPORE/BEIJING, Feb 25 (Reuters) - London copper prices raced past $6,500 a tonne for the first time since July on Monday, after U.S. President Donald Trump said he would delay an increase in tariffs on Chinese goods, while tin touched a 10-month peak after an accident-hit Chinese miner stopped production. Citing "substantial progress" in trade talks over the weekend, Trump said he would delay the planned tariff hike on March 1 and would plan a summit with Chinese President Xi Jinping in Florida to conclude an agreement, assuming both sides make more progress. Shanghai copper rose for a seventh day in eight but broker Jinrui Futures cautioned that while there were expectations of improved demand after the end of the off-season, current fundamentals did not provide strong support to prices. Import premiums for physical copper in China SMM-CUYP-CN slipped to as low as $52 a tonne on Friday, the lowest since May 2017. "The key to a sustained market rally is a recovery in demand," Jinrui Futures added. FUNDAMENTALS * LME COPPER: Three-month copper on the London Metal Exchange was up 0.6 percent at $6,513.50 a tonne as of 0717 GMT, having earlier touched $6,516.50 a tonne, the highest since July 4. The most-traded copper contract on the Shanghai Futures Exchange rose as much as 1.8 percent to its highest since Dec. 3 before closing up 1.6 percent at 50,520 yuan ($7,551.34) a tonne. * PERU: Chinese miner MMG Ltd said it will have to delay some shipments of copper concentrate from Matarani Port due to a blockade by an indigenous community of a road used to transport copper from the Las Bambas mine. * COPPER STOCKS: On-warrant LME copper inventories MCUSTX-TOTAL slumped by nearly half to 39,800 tonnes in one day, the lowest since August 2005, LME data showed on Friday. * TIN: LME tin rose as much as 0.9 percent to $21,695 a tonne, its highest since April 20, after a unit of Inner Mongolia Xingye Mining halted production following an accident at a mine on Saturday that killed 21 people. The unit produces tin, silver and copper, a statement said, while state-run news agency Xinhua said the mine also produced lead and zinc. * OTHER METALS: In a broad rally, all Shanghai base metals added more than 1 percent, with nickel hitting its highest since Oct. 24 and aluminium touching its highest since Dec. 27.
