The proposed widening of the Panama Canal is going to have a profound effect on the Gulf ports as well East coast ports. It is also going to change the neighboring countries to Panama ports to be a more vital link to US via rail. It is also going to have a major impact on the highway infrastructure in many ports in the US, Savannah and Charleston port authority's have already worked on partnerships between there two states to deepen there waterways to accommodate these new super container-ships.
Finally, trade zones are changing. Mexico is already seeing the benefits of US trade, Between the costs of labor and other expenses and the distance of China, it is interesting time for change.
On this same note look at what our NJ-NY Port of authority is doing in raising the Bayonne bridge 183 feet to accommodate these new super container ships, if they don't raise it they loose business to Ports that don't have bridge problems like Baltimore.
Let's not forget that the Suez Canal just in recent days have increased security through it's army and Police thus cutting the risk of piracy so they can show they are a formidable player in international trade.
Everyone of these items has something to do with change, throw into this mix what other countries are doing to be the next china, (India, Vietnam and South America) and you see a real mixed bag of events happening over the next five years.
Is there a chance after some thinking about these issue's that it might just pay to use a new term being thrown around "on-shoring" whereby history repeats itself and we might find ourselves becoming the viable option of manufacturing through sophisticated robotic plants, we already have a new car manufacturer using robotics in the state Washington and it happens to be the safest car on the road.
