The United States established diplomatic relations with Tanzania in 1961. The United States and Tanzania have a deep partnership characterized by mutual respect, mutual interest, shared values, and aspirations for a more peaceful and prosperous future. The United States respects Tanzania’s record of democratic progress, which has made it a model for the region and beyond, and supports Tanzania's continuing efforts to strengthen the institutions of democracy. The United States is committed to working with Tanzania on nutrition and food security, energy, women’s and children’s health, HIV/AIDS, and sustainable development. Several exchange programs welcome Tanzanians to the United States through the Fulbright, Humphrey, and English language program educational grants at the graduate and post-graduate levels. Other exchange programs promote artists, journalists, writers, civil servants, young leaders, musicians, and students. On the semi-autonomous islands of Zanzibar, the U.S. has sponsored English-teaching programs and provided science books to secondary students. The Ambassador's Fund for Cultural Preservation program has provided funding for restoration projects, including the historic ruins at Kilwa Kisiwani.
