Sir John Key does not believe US President Donald Trump intends to keep tariffs on most of the world.  

The former Prime Minister is speaking at the Ignite 25 Growth Summit business event in Auckland today.  

Key, who's supported Trump in the past, says the President is only focused on China in his new trade policies.  

He told Mike Hosking the stock, bond, and currency markets are not convinced that Trump is going to leave them where they are.
