This may not be true. 
My company sell our goods at a very low price because of our low overhead. There are always some buyers who will come to us to ask for a cut, failing which he will threaten to bring the business to our competitors.
Very painful to deal with this kind of customers. If don't bribe them, lose all the businesses; if bribe them, face legal problem if get caught

Big names like Mitsubishi, Samsung and China gas and oil corporation didn't do it, so, why Sembcorp marine?
