"There will be no production jobs lost as a result of this combination," said MAN chief executive Håkan Samuelsson in a statement.
"We have initiated this combination because we believe that a pooling of two strong groups with similar values but separate identities is the best way to safeguard our common future and secure employment in Sweden and Germany."
Samuelsson added that under his leadership "no business unit will subsidise another. That means that there will be no discrimination of Swedish employees in favour of Germans or vice versa."
MAN has launched a hostile takeover bid for Scania and the Swedish truck maker and labour representatives have suggested that the takeover would involve job cuts.
