LONDON, Oct 13 (Reuters) - Nickel prices hit a one-month high on Friday on concerns China might order further output cuts as it ramps up efforts to clean its skies, while aluminium gave back gains after rising on news a Chinese city had ordered capacity reductions.
China's Communist Party Congress takes place next week and markets expect Beijing could broaden efforts to eliminate more polluting mines and metal plants, especially during the winter months.
In aluminium news, the city of Binzhou, home to top global aluminium maker China Hongqiao Group, has ordered 2.57 million tonnes of annual smelting capacity to be closed this winter.
"The China environmental cuts are definitely having an impact. The concern is they could spread. On the nickel side there's been reports we may see capacity cuts in nickel pig iron," said Warren Patterson, commodities strategist at ING.
"The global economy is ticking along, China's come back from holidays more bullish (and) every data point we see out of China, out of the U.S., out of Europe, looks fairly positive."
China's import and export growth accelerated in September, data showed, suggesting the economy is still expanding at a healthy pace despite widespread forecasts of an eventual slowdown.
* NICKEL PRICE: Three-month nickel on the London Metal Exchange ended up 2.5 percent at $11,675, having hit a one-month high of $11,725.

* CHINA COMMODITY IMPORTS: China's factories splurged on imported commodities last month amid rising costs and tighter raw material supplies driven by Beijing's anti-pollution campaign. But the strength is unlikely to be sustained as many companies curb production during winter.
