The SAARC Food Bank is likely to be operational soon with the completion of ratification by the member states, reliable sources said. According to a highly placed source, among the member states of the South Asian Association of Regional Cooperation (SAARC), so far four -- Bangladesh, Pakistan, India and Sri Lanka -- have ratified the declaration for establishment of the proposed SAARC Food Bank. The declaration is now awaiting the ratification by the other SAARC nations.
