The Trade Minister says uncertainty around Donald Trump's tariffs is most concerning, following threats he'll impose a 100% tariff on all movies made outside the US. 

The US President didn't confirm when or how it could be enacted in a post on social media, which followed an initial threat on foreign-produced movies in May. 

Todd McClay told Mike Hosking he was in Malaysia last week with other trade ministers, who are all dealing with the rolling wall of announcements with no clarity. 

He says Trump's social media announcements are creating a lot of uncertainty, and Hollywood won't know what's going on.
