The Arusha Agreement was a treaty signed on 24 September 1969 in Arusha, Tanzania, between the European Community and the three East African states of Kenya, Uganda and Tanzania. The agreement entered into force on 1 January 1971, concomitant with the second Yaoundé Convention, with the aim of establishing better economic relations between the EC and the African states. At the end of their validity time, the Lomé Convention was signed which substituted the previous agreements and enlarged them to 46 ACP countries.
