Nicaragua has wanted a canal since the 19th century, and off and on has talked about building its own. The latest twist is that the Russians claim to be interested in helping. In the era of $100+ per barrel oil prices, Russia (not to mention Venezuela) made a wide range of promises to other countries. Now that it's low, these promises are even less likely to be kept. I guess the Russians figure a symbolic gesture never hurt anyone, but I'd be surprised if they put any significant amount into the project.
