U.S. prosecutors want Chang extradited to the U.S. to face trial, but the Mozambican government has engaged a South African law firm to fight those efforts and have him returned to Mozambique instead.
However, South Africa's justice minister filed an affidavit in July in which he announced that South Africa would oppose Chang's return to Mozambique because he has not yet been charged in his home country.
Chang faces charges that he was part of the government taking out large loans but did not make public. Their eventual disclosure in 2016 resulted in the International Monetary Fund withdrawing its support for Mozambique.
The extradition hearing has been scheduled for 16th to 17th October.
