Malaysia's biggest supermarket chain has announcedit will not sell products that are marked ‘palm oil-free.'The head of the company announced the move on Thursday.It is part of a campaign by Malaysiato protect the image of palm oil at home and in overseas markets.Malaysia is the world's second largest palm oil producer, after Indonesia.The world palm oil trade is said to be worth an estimated $60 billion.But in recent years, it has become the target of environmental activists.They say large areas of land, much of it rainforest, have been clearedto grow the trees that produce the valuable commodity.As a result, the European Union passed an act this yearrequiring the slow phase out of palm oil as a renewable fuel by 2030.The EU has linked intensive efforts to expand palm oil production to deforestation.In some areas, palm oil is used as a biodiesel fuel.But in almost 70 percent of the world,palm oil is used in cooking and food products, such as bread and pizza.Two countries, Malaysia and Indonesia, produce 85 percent of the world's palm oil.Now, the Malaysian government is considering banningall products that are marked ‘palm oil-free.'Ameer Ali Mydin is the managing director of Mydin Mohamed Holdings,which owns the supermarket chain.He said Mydin stores removed all products claiming to be anti-palm oil on Wednesday.He said the aim is to convey the importance of palm oil to the Malaysian economy.Ameer Ali recently told reporters, that his company "...must support palm oilbut must also make sure (to counter) the subtle messages,the marketing and branding exercises that people do..."He said the anti-palm oil products that were removed are all imported,but he would not say how many products were affected.Teresa Kok is Malaysia's minister of primary industries.She welcomed Mydin's campaign.She told reporters she hoped other stores in the country would follow suit.In July, Malaysia's government threatened an international schoolover spreading "anti-palm oil propaganda."And Indonesia, the world's biggest palm oil producer,told some businesses in Jakarta last monthto remove food products with "palm oil-free" labels from their stores.
