By systematically refusing to answer questions about abuses and dispossession in Sudan and Ethiopia the oil giant Lundin Petroleum and Sweden's minister for foreign affairs Carl Bildt have found a winning strategy, writes Kerstin Lundell, author of the award winning 'Business in Blood and Oil: Lundin Petroleum in Africa'. 'Based on earlier experiences, we find it's not of a constructive nature to comment on unsubstantiated claims about Lundin Petroleum and the corporation's business.' That's all the answer I've received for all the questions I've asked for the past four years about the company's knowledge of or involvement with all the events - the murders, the burning of entire villages - in Sudan and Ethiopia that I've encountered as I collected material for my book 'Business in Blood and Oil' and for articles in Process Nordic magazine.
