President Netumbo Nandi-Ndaitwah has likened corruption to treason.
The newly sworn-in president said this in her inauguration speech at State House in Windhoek on Friday.
She used a quote of former Tanzanian president Julius Nyerere, who stated that corruption should be seen as treason.
"And I agree," she said to the quote.
The president said corruption can lead to frustration which will ignite citizens to overthrow the government.
Nandi-Ndaitwah called for mutually beneficial relations with countries.
"We want win-win trade agreements in the region, continent and globally," she said.
Nandi-Ndaitwah further set out her priorities for her tenure, naming improving healthcare and education as well as growing investments.
