SINGAPORE/TOKYO, Nov 6 (Reuters) - About three years ago, Japanese oil trading firm Petro-Diamond Singapore (PDS) relocated to a bigger office in the 41-storey Millenia Tower as parent Mitsubishi Corp started combining its Tokyo trade operation with that in the city state.
As its traders entertained clients in the company's pantry facing Singapore's Marina Bay, the once-conservative PDS became the global book leader for the company's crude oil and fuel trading businesses last year, tripling its profits and assets from two years ago, according to Reuters interviews with company officials, trade sources and reviews of its financial records.
