LONDON, Nov 30 (Reuters) - Copper rose on Thursday on the back of upbeat manufacturing data from China, though it was on track to fall this month on concerns over slowing demand from the world's largest metals consumer.

Growth in China's manufacturing sector unexpectedly picked up in November despite a crackdown on air pollution and a cooling property market, the official Purchasing Managers' Index showed.

"We've had some slightly more encouraging data out of China," Danske Bank analyst Jens Pedersen said. "The official PMIs came out overnight slightly higher than consensus, so the market has taken that very well."

"There has been some uncertainty over whether growth in China would hold up or not, so that is why the market is trading on these key figures," he said.

Nickel has been the biggest faller among industrial metals so far this month, slipping nearly 8 percent to retrace some of October's hefty gains as traders bet that a rally based on hopes for rising electric vehicle demand had become overstretched.

* COPPER: Three-month London Metal Exchange copper was up 0.4 percent at $6,790 a tonne in official midday trading, but has fallen 0.8 percent so far in November.

* LME STOCKS: Copper stocks held in LME warehouses fell another 3,200 tonnes, data showed on Thursday, taking them to their lowest since July 2016 at 188,525 tonnes.

* COPPER TECHNICALS: LME copper is testing resistance at $6,792 after stabilising around a support zone of $6,713-$6,737 a tonne, Reuters technical analyst Wang Tao said. A break above here could spark a rise to $6,847.

* STRIKES: Workers at Southern Copper Corp in Peru said they completed a ninth day of a strike on Wednesday. A union at Teck Resources' Quebrada Blanca copper mine rejected a contract offer from the Canadian miner, increasing the likelihood of a strike.

* NICKEL: LME nickel was down 1.6 percent at $11,330 a tonne in official trading.

* ALUMINIUM: LME aluminium was untraded in official rings, but was last bid down 0.9 percent at $2,050 a tonne, off an earlier 3-1/2 month low of $2,039. It is down nearly 5 percent so far in November, its biggest monthly loss since May last year, but is still on track for its biggest annual rally since 2009.

* OTHER METALS: LME zinc was up 0.6 percent at $3,175 a tonne in official trading, while lead was up 1.7 percent at $2,477. In November, zinc has fallen 2.9 percent while lead is 2.8 percent higher. LME tin is up 0.3 percent at $19,580, and has risen 0.8 percent so far this month.
