The US needs to lift restrictions on British companies if they want a trade agreement with Britain, Boris Johnson said.
Traveling to the G7 summit in Biarritz, France, the PM said that "there are significant barriers to UK business in the US".
Mr. Johnson said he has already spoken with President Donald Trump about his concerns and will do so again when they meet on Sunday morning.
The Prime Minister will also hold talks with EU Council President Donald Tusk.
"There are tremendous opportunities for UK companies to open and praise the American market," said Johnson.
"We intend to take advantage of these opportunities, but our American friends must compromise and open up their approach as there are currently too many restrictions."
As an example of a limitation, Mr. Johnson stated, "Melton Mowbray Pork Pies who are sold in Thailand and Iceland, currently can not enter the US market because the administration of food and medicines, as I do not know, is limited. "
He continued," British peppers can not stay up at all enter the US market.

"British microbreweries are subject to a tax that does not apply to US microbreweries in the UK."

Mr. Johnson also discussed the possibility of a tax on internet giants after the French government had decided to authorize a digital tax service tax despite threats of retaliation by the US.
"Honestly, we need to do something to fairly and properly tax the online companies that make such tremendous revenue in our country," he told reporters. "We need to do something to make sure we tax them properly.
" I'm open to discussing how we do that, and I'm ready to listen to our American friends about the modalities, but we have to do something to tax her fairly.
