April 30 (UPI) -- President Donald Trump on Thursday lifted tariffs that he had levied but limited business between bourbon makers in Kentucky and Scotland.

Trump announced he was scrapping the tariffs after King Charles III and Queen Camilla were starting to wrap up their visit to the United States this week, which included the king addressing a joint session of Congress, a state dinner at the White House and a trip through Virginia before they head home.

King Charles and Queen Camilla have just wrapped up a four-day trip to the United States, which Trump scheduled and invited them for after a state dinner in the United Kingdom last year.

"In honor of the King and Queen of the United Kingdom ... I will be removing the Tariffs and Restrictions on Whiskey having to do with Scotland's ability to work with the Commonwealth of Kentucky on Whiskey and Bourbon, two very important Industries within Scotland and Kentucky," Trump said in a post on Truth Social.

"People have wanted to do this for a long time, in that there had been great Inter-Country Trade, especially having to do with the Wooden Barrels used," he said.
