Nicaragua doesn't really need another telecommunications company. I believe the planned sat/phone investment was meant as China's dangling carrot for Nicaragua. The reality is they have two Mobile phone carriers that are throughout the country, a 4G network in the major cities built by Russian Yota, a fiber hub on the coast, digital landline penetration throughout the country via Claro, two satellite TV services (SkyTV and Claro, competing), coax cable in the major cities, DSL in most areas, etc.
Now Wang comes to Nicaragua exploring these matters and he hears about something more grand, a grand canal-- a project that would make money, give China a ton of influence in the area, and provide great trade leverage. Indeed, China could aid exports by providing its companies with credit to cross the canal allowing a portion of shipping costs to be paid for after the fact. This enables companies to export, receive payment on arrival, then pay the canal costs. That can't be done with Panama Canal, it's pay the $15,000 to get your boat through.
However, even if there was no canal, land in Bluefields will go up in value once the highway is completed. The highway is being constructed NOW.
