BEIJING, Nov 28 (Reuters) - Prices of base metals slid on Monday as the U.S. dollar strengthened, with protests in several Chinese cities against the country's strict COVID-19 curbs adding to investors' fears.

Three-month copper on the London Metal Exchange was down 1.1% at $7,921 a tonne, as of 0817 GMT, while the most-traded January copper contract on the Shanghai Futures Exchange shed 1.4% to 64,130 yuan ($8,907.93) a tonne.

Hundreds of demonstrators and police clashed in Shanghai on Sunday night as protests over China's stringent COVID curbs flared for a third day and spread to several cities in the wake of a deadly fire in the country's far west.

The protests raised worries about management of the virus in the world's second-largest economy and sent Asian stocks lower on Monday. The protests also led investors towards the safe-haven dollar, while the Chinese yuan to a more than two-week lowagainst the dollar.

A stronger greenback makes it more expensive for non-dollar holders to buy dollar-priced commodities.

"We've not had any risk-on reasons except the RRR cut last Friday which saw markets rally, although with such drastic FX moves (we) have seen a revaluation and rebalance of portfolios as LME volumes pick-up for copper and ali," said Zenon Ho at Marex Metals desk in a note.

China's industrial firms saw overall profits decline further in the January-October period as COVID-19 outbreaks flared up and cities imposed new virus curbs, including targeted lockdowns, dampening economic activity.

Among other metals, LME aluminium slid 0.4% to $2,354 a tonne, zinc dropped 0.6% to $2,904.5 a tonne and nickel slipped 1.2% to $25,100 a tonne.

The London Metal Exchange (LME) hopes to resume trading of its nickel contract during Asian hours within the next two weeks, an executive said on Monday.

The world's largest and oldest forum for trading metals, the LME was forced to suspend the nickel market and cancel all trades on March 8, after prices spiked more than 50% to hit a record above $100,000 a tonne within a few hours.

SHFE nickel was down 2.8% at 193,250 yuan a tonne, aluminium dropped 1.1% to 18,690 yuan a tonne, zinc slipped 0.2% to 23,565 yuan a tonne, and tin shed 1.3% to 182,060 yuan a tonne.
