The World Food Programme is the largest purchaser of food and services in developing countries among UN agencies and a major supporter of South-South trade. WFP has sought to increase this activity, and total food purchases from developing countries have increased from 0.7 million tonnes, valued at US$157 million in 1989, to over one million tonnes, valued at US$263 million, in 1993. The 1993 figures correspond to two-thirds of WFP's total food purchases for the year.
