This one features 'Eric', a presumably fictional investor who has apparently invested in an unnamed Latvian company already and now enjoys multiple benefits.
These include use of the RIX Airport City aviation hub (not built yet, stage one is tentatively scheduled for completion in 2028, though it is likely to be later as it relies upon...), a "modern and fast railway connection with the rest of Europe" (Rail Baltica, not built yet, tentatively scheduled for 2030 though it is likely to be later) and "Michelin level restaurants".
Accompanying images show Eric is the sort of investor who likes to cosplay as Aquaman to demonstrate his "investor superpowers".
It wouldn't be any standard Latvian investment pitch of the last decade without inserting a bit about having "the longest sandy beach" in Europe, though the familiar claim that this beach is "500 km +" in length is doubtful given that the entire length of the Latvian coastline is around 496 km and by no means all of it is sandy beach easily accessible to the public. However, Eric's aquatic superpowers likely give him an advantage in this regard.
According to the Encyclopedia of the World's Coastal Landforms, there is about 240 km of sandy beach along the Latvian coast and a mere 80 km of that is classified as having high recreational potential.
Nevertheless, viewers are assured that non-existent Eric has "ambitious plans" in the areas of energy, transport, and knowledge-intensive businesses without getting too specific about what his plans are in the realm of fact, rather than the sandy seabed of his undersea kingdom.
