HANOI, March 3 (Reuters) - Shanghai aluminium prices rose to a near 9-1/2-year high on Wednesday, buoyed by concerns of supply cuts in China, the world's biggest user and producer of the metal.

The most-traded April aluminium contract on the Shanghai Futures Exchange ended 4.2% higher at 17,640 yuan ($2,729.09) a tonne, hovering near its highest level since August 2011 of 17,695 yuan a tonne it last hit on Feb. 26.

Three-month aluminium on the London Metal Exchange rose 1.1% to $2,235 a tonne by 0712 GMT. The contract jumped 3.9% on Tuesday.

China's Inner Mongolia, a major aluminium producing region, will stop reviewing new projects in industries which consume large amounts of energy, including aluminium, as it attempts to meet energy efficiency targets.

"Aluminium supplies are already tight due to speculation that China will close the aluminium smelters that are due to not meeting environmental regulations," a Singapore-based trader said.

"Every physical customer is asking around for aluminium warrants at the moment."
