Welsh beef was on the menu in Havana, Cuba, this week.
The branded meat was served at a roast beef dinner in the British Embassy, said farmer co-operative Welsh Lamb and Beef Promotions.
The move follows lobbying by the Hull and Humber Chamber of Commerce to lift Cuba's embargo on imports of British meat products.
The campaign has resulted in the Cuban government agreeing to allow samples of British meat products to be imported to the embassy for promotional events.
The beef has been sourced from Welsh farms and supplied by St Merryn Foods of Merthyr Tydfil. Don Thomas, mD of WL&BP said: "This event gives Wales the opportunity to lay down the marker for Welsh beef, which is gaining in its recognition as an international quality brand.
"The costs are negligible to support such an event as this, however the longer term opportunity could be significant."
