For hundreds of years, people have dreamed of building a canal across Nicaragua, conquering the volatile land of volcanoes and rainforests and breaking Panama's monopoly on global shipping.
Yesterday that dream came a step closer to reality as a Chinese entrepreneur unveiled his route for a 273km, $50 billion waterway from the Pacific to the Caribbean.
If Wang Jing pulls off the feat, it will rank as one of the greatest engineering marvels in history.
Sitting in the offices of his telecommunications company north of Beijing, Wang, 40, is clearly very determined. "I am 100 per cent certain the construction will begin in December 2014 and we will finish in five years in 2019," he said.
He added that while a feasibility report was unfinished, "the framework" of the project had been decided.
