Aldi is to step up the rate at which it open stores in the US.

The discount retail giant, which has 1,300 outlets, in 32 US states, said it planned to open an average of 130 stores a year for the next five years, up from a rate of 80.

The privately-owned German grocer said it would spend more than US$3bn buying land, facilities and equipment.

When the expansion is complete, Aldi expects to have stores "coast-to-coast". It expects to create more than 10,000 new jobs at its stores.

Jason Hart, president of Aldi's US business, said the retailer wanted to meet "growing demand" across the US.

He said: "Recently, we successfully entered new markets such as Houston, and expanded our presence in competitive markets like south Florida and New York City. At Aldi, we believe that great quality can be affordable, and we are eager to bring the Aldi difference to new markets like Southern California."

Aldi has also decided to build its regional headquarters and distribution centre in Moreno Valley in California.
