LONDON- Copper prices rose to their highest in two weeks on Tuesday, buoyed by hopes that more economic stimulus from China would boost demand from the world's top consumer of the metal.

China, which accounts for about half of global metals demand, will step up financial support for industries, companies and people affected by COVID-19 outbreaks, the central bank said on Monday in its latest move to cushion economic slowdown.

Also supporting copper prices was news that MMG's Las Bambas mine in Peru, which accounts for 2% of global supply, would suspend operations from April 20 because of recurring disruptions from impoverished local communities demanding higher financial contributions from the mine.

Southern Copper's Peruvian mine has been closed for six weeks because of its own standoff with protesters.

"Both China's new measures to stimulate its economy as well as the Peru mine disruptions are broadly supporting copper and other metals," said Bank of China International's head of commodity strategy, Amelia Fu.

Benchmark prices for copper on the London Metal Exchange (LME) climbed 0.9% to $10,402 a tonne by 1126 GMT.

PANDEMIC: Rising COVID-19 cases in China have sparked concerns over an economic slowdown. Mainland China reported 21,600 new infections on April 18.

INVENTORIES: Climbing inventories in LME-approved warehouses put a lid on prices, but global supplies remain at historically low levels. Total stocks of copper rose to their highest since November, up 8,150 tonnes to 118,825 tonnes.

Inventories in warehouses monitored by the Shanghai Futures Exchange have fallen to a two-month low at 88,682 tonnes.

NICKEL: The global nickel market registered a surplus of 10,500 tonnes in February, compared with a deficit of 5,700 tonnes in the same month last year, data from the International Nickel Study Group showed on Monday.

OTHER METALS: LME aluminium rose 1.2% to $3,321 a tonne, zinc was up 1% at $4,454, lead eased by 0.2% to $2,440, tin gained 0.9% to $43,445 and nickel edged up by 1.5% to $33,685.
