Geneva - Zimbabwe President Robert Mugabe has long faced United States sanctions over his government's human rights abuses. But the World Health Organisation's new chief is making the longtime African leader a "goodwill ambassador."With Mugabe on hand, WHO director-general Tedros Ghebreyesus told a conference in Uruguay this week on non-communicable diseases that he'd agreed to be a "goodwill ambassador on NCDs."Tedros, an Ethiopian who became WHO's first African director-general this year, said Mugabe could use the role "to influence his peers in his region to prioritise NCDs."A WHO spokesperson confirmed the comments to The Associated Press on Friday.The US in 2003 imposed targeted sanctions, a travel ban and an asset freeze against Mugabe and close associates, citing his government's rights abuses and evidence of electoral fraud.
