South Africa is blocking arms sales to Saudi Arabia and the United Arab Emirates (UAE) in a dispute that could cost it billions of US dollars.

Both countries have been accused of transferring weapons that they bought from South Africa for use in the war in Yemen. That violates the terms of the export agreement which does not allow weapons to be passed on to a third party.

South African officials should also be able to inspect weapons facilities, but Saudi Arabia and the UAE have both refused to give them access.

Na’eem Jeenah, executive director of the Afro-Middle East Centre in Johannesburg, South Africa, talks to Al Jazeera about the developments.
