The US President-elect is pledging to hit Canada and Mexico with large taxes.
Donald Trump says of many first executive orders, one will be charging the neighbouring countries 25% goods tariffs.
He says they'll continue until they clamp down on illegal border crossings of drugs and migrants.
US Correspondent Richard Arnold told Mike Hosking that the last time Trump played the tariff game it was with China, which resulted in Trump having to give US farmers bailouts worth $23 billion.
He says economists are speculating that the tariffs taking shape in the way Trump is illuding could add up to $2,600 extra a year for consumers.
