Carlos ‘Sonny’ Dominguez has been finance minister of the Philippines since 2016, serving under president Rodrigo Duterte. He has been a key architect of ‘Dutertenomics’, a catch-all term for a mix of policies including cutting red tape, reforming the tax system and improving the skills of the country’s workers. But the landmark economic policy of Dutertenomics is Build Build Build, an ambitious infrastructure spending programme.
