Trump was asked about negotiations with China over the tariffs and claimed that the Chinese government has been taking away many of America's industries such as microchips.

"I would like to say they can do better in terms of the bottom line. We would like to see China opened up so we can compete in China and give people something that they've never had," he said.

"Access to something that would be great for the world and great for our businesses and I think it would be great for friendship," he added.

Trump credited Brexit for helping to get the tentative deal with the U.K. and bashed the European Union.

"We intend to make a deal with Europe. We have found that the European Union treated us extremely unfairly. They are very difficult, and hurt themselves in doing so and very much want to make a deal. We're dealing with them currently," he said.

Trump was asked if the trade deal with the U.K. would affect his threats of tariffing films made outside of the U.S.

The U.S. cannot impose a direct tax on a film as it would be a durable good, according to economic experts.

Trump claimed that tariffs on films was a "separate discussion" from the British deal.

"They all live here, the money and everything comes from here but [moviemakers] make them in other countries," Trump said. "We'll do something to bring them back maybe to a large extent but James bond has nothing to worry about, that I can tell you."

During the news conference, Trump and Starmer emphasized that the trade deal between their nations is not finalized.

"The final details are being written up," Trump said.

"And yes, we could iron out some of the details, but fantastic platform here, including on the tech side where I think I can say we are the only two western countries with trillion-dollar sectors when it comes to tech," the prime minister later said.
