Edgar Lungu and his Rwandan counterpart Paul Kagame have signed an extradition treaty between Zambia and Rwanda.
The treaty will allow Zambia to hand over Rwandese based in Zambia back to their country to face trial once requested by the government of Rwanda.
A number of Rwandese in Lusaka closed their shops in Lusaka today and went into hiding for fear of the Rwandan intelligence officers who have flooded Lusaka as Rwandan President Paul Kagame is visiting Zambia.
Other agreements that have been signed include an agreement on defence and security cooperation and one on air services.
A number of Rwandese refuges have refused to go back to Rwanda and opted to stay in Zambia at the end of their refugee status for fear of being killed if they go back.
