In April 1992, Ms. Hoang Thi Khanh, President of the Ho Chi Minh City Confederation of Labor at that time, was invited by Professor Yunus – Grameen Bank to attend a seminar on banking experience for the working poor and low-income members of the community. Later, CEP was officially a member to join the global Grameen network. Since then, CEP had always been supported by Grameen Bank many times: In September 1992, the Ho Chi Minh City Confederation of Labor sent 10 officers to study the model “Surveying and selecting subjects of the project” of Grameen Bank in Bangladesh. In April 1994, Grameen Bank loaned CEP $50,000 without interest, for a period of 5 years. In December 1995, Grameen Bank invited CEP to attend a workshop on “Developing a micro-credit implementation plan” in Bangladesh and agreed to lend CEP USD 123,500 with preferential interest rates. In March 1996, Grameen Bank invited CEP to attend a workshop on “Prevention of Delinquency” in Bangladesh. In 2002, CEP was invited to study the Grameen 2 model, the product improvement model in the development process.
