NAIROBI - South Sudan's President Salva Kiir has sacked the country's finance minister who was just four months into the job, state-owned television reported, the sixth replacement in the post since 2020.

Kiir gave no reason for firing Awow Daniel Chuong, who was appointed in mid March this year, the report said late on Wednesday, and economist Marial Deng has been tapped to replace him as finance minister.

South Sudan's economy has been under pressure in recent years amid communal violence, with crude oil export revenue having dwindled since a 2013-2018 civil war and more recently export disruptions due to conflict in neighboring Sudan.
