The company keen to complete the Formula 1 track near the town of Sliven has obtained a satellite picture of the area in south Bulgaria.
Dutch representatives of the prospective investors have reportedly visited the town over last weekend to meet with Mayor Yordan Lechkov, once prominent national football player.
Western businesses have shown interest in fuelling EUR 200 M to finish the track construction initiated 20 years ago.
The local military airport of Burshen is seen as a landmark for the completion of the overall project, but unless it turns into a civil airport, the F1 track could not be completed, Lechkov pointed out.
