Brussels, 02/03/2000 (Agence Europe) - According to European sources the European Commission could oppose, on the 14 March, the merger of the Swedish truck manufacturers Volvo and Scania. The new undertakings presented a week ago by the manufacturers would not be enough to remove the fears on the compatibility of the operation with European competition regulations. The European services also fear that the two manufacturers may dominate the truck and bus market in Scandinavia, where the new group represents more than 60% of the market. The undertaking to open the dealership networks to competitors was not enough to convince the Commission. The deadline to put forward new undertakings has passed but the discussions continue between the European institution, the Swedish authorities and the two manufacturers.
