"We are focused on innovating and adapting our supply chain to create greater efficiencies in our distribution models."

NEW ZEALAND: Progressive Enterprises, the company behind the Woolworths, Foodtown and Countdown supermarket brands in New Zealand, is to bring them all under the Countdown fascia. It has been given a new grey and green stylised apple logo as part of the move.

"We looked very carefully at which of our three brand names to go forward with, and we are absolutely certain that Countdown is what smart shoppers want," said managing director Peter Smith. Progressive Enterprises has 150 stores across New Zealand and said the change, which will include revamping some stores, would cost around $1bn (£443m).

CHINA: A spate of stabbings in Beijing has prompted a ban on knife sales at major supermarkets until mid October. According to state media, knives were removed from shelves at Carrefour, Wal-Mart, Jingkelong, and Tiankelong supermarkets. It follows the stabbing of 16 people by a knife-wielding man last week near Tian'anmen Square. Two days later a woman was stabbed by another attacker. Police have stepped up patrols of the popular tourist area in recent days, although Beijing is generally regarded as a safe city in which to work and travel. The ban comes as China clamps down on security in the run-up to celebrations of 60 years of communism.
