When high-flying Hong Kong investment bank Peregrine decided to set up a joint venture in South Korea six years ago, its partner must have seemed an excellent choice. A medium-sized conglomerate, the Dongbang group was a reasonably well focused business, the leading maker of cooking oil, a producer of food materials and owner of a restaurant chain.

A huge advert for the bank bears down in passport control outside Sheremetyevo airport and also appears on the back of cloakroom tags at the Bolshoi theatre, accompanied by the slogan "the customer is king at our bank" - a concept new to anyone accustomed to the Byzantine ways of Russian banks.
