No.22/QD/NH5 issued by the Governor of the State Bank of Vietnam (SBV) Over more than 15 year operating, VIB has been consistently in the top joint stock commercial banks in Vietnam The year 2010 marked a significant development of VIB by a strategic partnership with the Commonwealth Bank of Australia – a leading retailer of Australia In order to maintain exclusive position, since early 2011, VIB has set up a newly dedicated Foreign Direct Investment Division within VIB to serve foreign invested companies in Vietnam Given the fact that there are huge opportunities for VIB as foreign direct investment is increasing year by year in Vietnam, VIB has to realize its internal and external environment, their strengths and weakness so as to compete in a very huge but severe market with a lot of big & experienced competitors This thesis is carried out to assess the current marketing strategy of VIB FDI banking and provide some recommendations for FDI banking so as to obtained objectives assigned by the Board of Directors By determining the marketing segmentation using the quantitative and qualitative combination methodology, the project explores that VIB is still a new brand name to FDI enterprises in Vietnam and most FDI enterprises are not impressed by VIB quality of services Thus, it is necessary to suggest a suitable marketing strategy so VIB can compete effectively in this severe market vi TABLE OF CONTENTS COMMITMENT i ACKNOWLEDGEMENTS iii TUTOR’S COMMENTS iv EXECUTIVE SUMMARY v TABLE OF CONTENTS v LIST OF ABBREVIATIONS ix LIST OF FIGURES xi LIST OF TABLES xii Chapter

objectives 2012 - 2015 56 79 purpose of this project is to suggest a more appropriate and effective marketing strategy for VIB FDI Banking to improve revenue and win market share regardless of the fierce competition from foreign banks and state owned commercial banks The literature review helps to understand some concepts of marketing strategy and marketing environment The theory of marketing mix applied in this study is usually used for banking industry Moreover, the study on B2B marketing helps us to understand more about enterprises’ structure of demand, their reactions over changes in marketing environment as well as their decision making process About project methods, the project adopts three methodologies: the desk research, Qualitative and Quantitative research The desk research helps to know more about the Banking industry, the features of FDI enterprises and the current competitions of banks proving services to FDI enterprises The Qualitative research is implemented by in-dept interview with FDI banking RMs, Team managers to know more about what FDI customers expect about banking services, how they make a decision, how to win long term relationships and trust from FDI customers The quantitative research is conducted by delivering questionnaire to VIB’s current FDI customers to find out whether they are satisfied about VIB services and what they want VIB to change for better improvements From analyzing of VIB FDI banking current performance, competitors as well as customers, some useful findings reveals The first finding indicates that FDI customers only have relationship with those they really trust and VIB’s brand awareness and reputation is very weak in Vietnam banking market In term of competition, it is very hard for us to compete with foreign banks and state-owned banks which already have good reputation in Vietnam It is a very long step for VIB to build up our brands and reputation to compete in this fierce market Another finding reviews that utilizing our human resources together with right strategy and internal cooperation will help us to win customers and performance Through our RM and CS teams, we will first win relationship with FDI customers Good strategy and internal cooperation will make customer gradually trust about 80 VIB services and build up long term relationships with us These three elements will become our key success factors in the long term In conclusion, we think that the following key initiatives will help us to win success in this challenging but attractive segments, they are: Grow revenue - Develop Factoring and FX product tailor-made for FDI customer - Establishment of Korean Desk, Japanese Desk - Grow volume through commission scheme (IZ/EPZs boards), tactical moves, in line with market situation - Launch regular direct incentive programs in FX, Deposits - Product roll-out strategic plans for FX, Loan, Deposit, Factoring, L/C Aggressive Customer Acquisition and Reactivation - Recruitment of the right staffs for each team - Alliance with other front line sales team for cross selling - Customer campaigns: • • Co-operation with IZ/EPZs • - Co-branded card with retailers and hospitality service providers Factoring for SMEs Road show at embassies, Amcham, Eurocham, Auscham, KOTRA, Taiwanese Trade Association - Memorandum on Cooperation with Auditing, Legal firms Optimize
