METALS-Copper prices steady as dollar weakens; China data in focus

MELBOURNE, May 23 (Reuters) - London copper held near its highest in three weeks on Tuesday as the dollar fell, with focus shifting to an upcoming monthly breakdown of China trade data.


* London Metal Exchange copper was flat at $5,706 a tonne at 0135 GMT, after a slightly firmer close in the previous session when it touched the highest since May 3 at $5,720 a tonne.

* Shanghai Futures Exchange copper held gains of half a percent at 46,050 yuan ($6,687) a tonne.

* LME zinc and lead were also buoyed by a positive tone in steel, up 0.7 and 1 percent respectively, after China pledged to cut polluting factories.

* Nearby tightness in lead spreads dissolved, falling from a $34.50 premium for cash over the three-month contract in late April to a 23.25 discount overnight, which was the widest contango since July 2014 and which may flag a big delivery into LME exchange warehouses. <CMPB0-3>

* The euro hovered near a six-month high against the dollar on Tuesday after German Chancellor Angela Merkel said the currency was "too weak." A weaker dollar makes commodities, priced in dollars, more affordable for holders of other currencies.

* The Flash Markit/Nikkei Japan Manufacturing Purchasing Managers Index (PMI) fell to 52.0 in May on a seasonally adjusted basis, from a final 52.7 in the previous month.

* Asian countries disagreed over a China-backed free trade deal at talks on Monday, raising questions over a target for concluding negotiations by the end of the year.

* The global world refined copper market showed a 93,000 tonnes surplus in February, compared with a 55,000 tonnes surplus in January, the International Copper Study Group (ICSG) said in its latest monthly bulletin.
