Throughout the centuries the Kenyan Coast has played host to many merchants and explorers. Among the cities that line the Kenyan coast is the City of Malindi. It has remained an important Swahili settlement since the 14th century and once rivaled Mombasa for dominance in this part of East Africa. Malindi has traditionally been a friendly port city for foreign powers. In 1414, the Arab Sultan of Malindi initiated diplomatic relations with Ming Dynasty China during the voyages of the explorer Zheng He.[34] Malindi authorities welcomed Portuguese explorer, Vasco da Gama, in 1498.
