Peter Mandelson, the British ambassador to the U.S., told reporters that the U.K. is committed to "reducing tariffs and non-tariff barriers."

"This is a continuing picture, it is a movie, not a still picture. A movie, it continues. We're both committed to freeing up trade between our countries," he said.

"The point about this deal is that it provides very good template and very good launch pad for what we can continue to do and build on in the future," Mandelson added.

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."
