Since 1970, the share of high-value products (HVP's) in developing countries’ agricultural exports has increased. Developing countries remain a relatively small market for U.S. HVP exports, while their HVP exports to the United States have expanded. Developing countries are significant competitors in HVP trade and their export market share in the EC-12 and Japan is generally higher than the U.S. share. HVP market access to industrial countries is an important issue for the United States and developing countries in the 1990's.
