entry-strategies for emerging markets

Could you explain how entry-strategies for emerging markets ought to be carefully developed to avoid risk of being victims of micro and macro-economic crises that frequently pops out in developing countries? It would also be interesting to see how MNC’s deal with corrupt government officials to get quick legal and essential services especially where bureaucracy is a norm. There is a general belief that emerging markets are corrupt. I wonder what your view is, especially with the Nigerian experience. It is the people who are corrupt or the MNCs which encourage corruption?
