The third session of the Namibia-South Africa Bi-National Commission has been postponed until further notice.
The meeting was scheduled to take place in Windhoek from Tuesday to Friday next week.
The Ministry of International Relations and Cooperation says it will communicate new dates for the meeting once both countries have agreed on that.
The meeting was to be co-chaired by president Hage Geingob and South African president Cyril Ramaphosa, who was to lead his country's delegation.
The two presidents have over the past weeks been caught up in a developing scandal about the alleged theft of US$4 million (about N$64 million) by Namibian burglars from Ramaphosa's farm in South Africa's Limpopo province.
