MELBOURNE, July 23 (Reuters) - London copper eased on Monday but held above a one-year low hit last week on mounting concerns that escalating trade tariff spats could dent demand, although a weaker dollar cushioned losses.
* LME COPPER: London Metal Exchange copper eased by 0.1 percent to $6,137 a tonne by 0520 GMT, after prices last week fell for the sixth week in a row, hitting the lowest in a year at $5,988 on Thursday.
* SHANGHAI COPPER: Shanghai Futures Exchange copper was up 1.1 percent at 48,890 yuan ($7,233) a tonne.
* TARIFFS: U.S. President Donald Trump on Friday said he was ready to impose tariffs on all $500 billion of imported goods from China, threatening to escalate a clash over trade policy that has unnerved financial markets.
* ANTI-DUMPING PROBE: China on Monday launched an anti-dumping probe into stainless steel imports worth $1.3 billion, including from a privately owned Chinese mill with operations offshore, after complaints that a flood of product has damaged the local industry.
* GLOBAL ECONOMY: The International Monetary Fund (IMF) warned world economic leaders on Saturday that a recent wave of trade tariffs would significantly harm global growth, a day after Trump threatened a major escalation in a dispute with China.
* ZINC: LME zinc surged as shorts were forced to cover and due to a shortfall of available immediate supply. LME data showed a large short holding in the futures report, while lending guidance is enforced with a single holder of more than half LME metal. <0#LME-FBR> <0#LME-WHL>
