Dumfries and Galloway Council are welcoming visitors from Hungary, who are visiting the region as part of "100% RES (Renewable Energy Source) Communities" project.
The Hungarian partners will be shown highlights of the region's current sustainable energy projects and enterprises.
Dumfries and Galloway is representing Scotland on a European platform, as the town is the only Scottish region to take part in the project.
Deputy First Minister Nicola Sturgeon has been reacting to David Cameron's views on Trident and has said the Prime Minister is 'out of touch':
As part of his visit to Scotland, David Cameron is due to visit HMS Victorious, a Royal Navy submarine which keeps Trident nuclear missiles continuously at sea.
The Scottish National Party say they would scrap Trident in an independent Scotland.
However, Mr Cameron says it would be 'foolish' to abandon it because of the threat of nuclear attack from North Korea.
The Prime Minister will say the UK is 'stronger and safer together' as he visits Scotland today.
Speaking ahead of a trip to the offices of a defence contractor, David Cameron said:
Meanwhile, ahead of the visit, Scotland's Deputy First Minister has stepped up calls for David Cameron to agree to a live TV debate with Alex Salmond on Scottish Independence.
The former chancellor, Alistair Darling, believes that during these economically 'turbulent times' that the 'crucial argument' surrounding independence is that the UK as a whole will operate better in terms of the economy and jobs, compared to if Scotland left the union.
The leader of the UK 'Better Together' campaign and former Chancellor, Alistair Darling, is meeting with small businesses in Dumfries.
The visit is part of his tour of Scotland where he is hearing the views of business people on independence.
Mr Darling is due to speak with local businesses at a meeting organised by the Dumfries and Galloway Chamber of Commerce, before visiting the manufacturing site of Dupont Teijin Films.
