Mayor of Barking and Dagenham, Cllr Peter Chand and the Leader of the Council, Cllr Darren Rodwell planted the tree, marking 73 years of close friendship with the German city.
The two communities have been officially twinned for 41 years.
Twinning, which brings together towns or cities so they can learn from each other, is particularly important to the Mayor.
Cllr Peter Chand said: “We have a special bond with Witten as our twinned town.
“It is an honour to have planted this friendship tree to cement our strong ties and ever-growing friendship.”
